When you’re raising twins, it’s almost impossible not to compare them sometimes. You see one climbing confidently onto the sofa while the other is still figuring out how to get up. One starts talking in little sentences while the other communicates through a combination of single words, gestures, and very determined pointing. One seems ready to try everything, while the other prefers to watch first.
And because they’re twins, the differences can feel especially noticeable. They’re the same age, they live in the same home, and they experience many of the same things. So why does one seem to be racing ahead while the other is taking a different route?
Handling developmental gaps between twins can bring up a surprising mix of emotions, from pride in one child’s progress to worry about the other. You may wonder whether you’re doing enough to support the twin who seems to be struggling, or whether giving that child extra attention will make the other feel left out.
The important thing to remember is that twins are two individual children, not one developmental unit. They don’t need to reach every milestone at the same time, and supporting one child doesn’t mean you’re holding the other back.
The goal is to meet each child where they are, without turning their differences into labels that follow them as they grow.
Why Twins Don’t Always Reach Milestones at the Same Time
Even though twins share a birthday, they don’t necessarily develop at the same pace.
Children develop across several areas, including language, movement, social interaction, emotional regulation, problem-solving, and independence. A child may be ahead in one area and need more time in another. There isn’t one universal pattern that every toddler follows.
Your twins also have their own personalities, interests, and temperaments. One might be naturally adventurous and eager to try something new, while the other takes time to observe before joining in. One might love books and talking, while the other spends hours exploring how things fit together.
Different interests can lead to different opportunities to practise particular skills, too.
There may also be differences related to birth circumstances, health, individual experiences, or whether your twins were born prematurely. For twins born early, healthcare professionals may consider corrected age when assessing development, particularly during the first two years.
None of this means that every developmental difference should be dismissed as a normal variation. It simply means that being behind a sibling isn’t, by itself, enough information to determine whether a child has a developmental delay.
Look at each child’s progress over time, rather than using their twin as the measuring stick.
The Trap of Comparing Your Twins
Comparison can happen before you even realize you’re doing it.
You might find yourself thinking, “Her sister was doing that months ago,” or “Why can he do this but his brother can’t?” Sometimes the comparisons are private thoughts. Other times, they slip into conversations with family members, childcare providers, or even the children themselves.
It’s understandable. When you have two children of the same age in front of you every day, their differences are difficult to ignore.
But constant comparison can make you focus on what one child isn’t doing instead of noticing what they are learning.
It can also create an unhelpful family narrative. One twin becomes the clever one, the athletic one, or the independent one. The other becomes the quiet one, the baby, or the one who needs extra help.
These descriptions might seem harmless, especially when they’re said affectionately. But children can begin to absorb the roles adults assign to them. A child repeatedly described as the one who struggles may become less willing to try something difficult. The child who is always praised for being ahead may feel pressure to keep performing.
You don’t have to pretend the differences aren’t there. You can acknowledge that one child is currently using more words or climbing more confidently without turning that observation into a statement about who they are.
Instead of thinking, “She’s the clever one,” try, “She’s really interested in puzzles right now.”
Instead of saying, “He’s the slow one,” remind yourself, “He’s working on this skill, and I’ll support him as he learns.”
One describes a child as a fixed type of person. The other recognizes a skill that can develop.
That distinction matters.
If you find yourself comparing your children more often than you’d like, you’re not alone. When two children are the same age and share so much of their daily lives, it’s easy to turn ordinary milestones into a competition without meaning to. Recognizing this habit is the first step toward changing it. Read more about Comparing Twins: How to Stop (and Why It Happens).
How to Support the Twin Who Needs More Help
If one of your twins seems to be struggling with a particular skill, your instinct may be to spend more time practising it. That can be helpful, but it’s important to start by understanding what your child actually needs.
For everyday skills, look for small, natural opportunities to practise during your normal routine.
If one twin is less confident with dressing, let them try pulling up their trousers or putting on their shoes while you help with the trickier parts. If they’re working on language, talk about what you’re doing together, read books, sing songs, and give them time to respond without immediately speaking for them.
If one child struggles with activities that their sibling finds easy, break the task into smaller steps. Offer encouragement when they try, not only when they succeed.
You don’t need to turn your living room into a therapy centre or spend every afternoon running developmental exercises. Ordinary interactions, play, and opportunities to participate in family life can all support learning.
Just as importantly, don’t assume you need to teach the skill because the other twin already has it. Consider whether your child is showing progress, whether the skill is appropriate for their developmental stage, and whether you have any concerns that warrant professional advice.
If you’re worried about a milestone or notice that your child has lost a skill they previously had, speak with your healthcare provider rather than waiting for them to catch up to their twin.
Supporting your child means responding to their individual needs, not trying to make them match their sibling.
Give Each Twin Individual Attention
When you’re raising twins, individual attention can feel like a luxury. There are meals to prepare, clothes to change, toys to pick up, and two children who somehow always need something at precisely the same time.
Still, even small moments of one-on-one attention can help you understand each child’s interests, strengths, and challenges.
You don’t need to schedule elaborate solo outings. Ten minutes of reading with one twin while the other plays nearby, a short walk with just one child, or letting each child choose an activity on different days can create opportunities to connect individually.
These moments can also make it easier to notice what your child enjoys and where they might need support. When you’re constantly managing both children together, it’s easy for the more vocal or demanding twin to dominate your attention.
Try to notice whether one child regularly gets more opportunities to speak, make choices, or try something independently. The quieter twin may need a little more time to respond, while the more confident twin may need opportunities to practise waiting.
Individual attention isn’t about dividing every minute equally. It’s about making sure both children feel seen.
And if you can’t manage one-on-one time every day, don’t turn that into another thing to feel guilty about. You’re raising two toddlers, not running a perfectly balanced attention spreadsheet.
Sometimes, one twin genuinely needs more support or attention than the other, whether because of their temperament, current challenges, or stage of development. Finding a balance can be difficult when both children need you at once. If you’re struggling with this in your own family, read When One Twin Toddler Needs More Attention for practical ways to respond to each child’s needs without leaving the other feeling overlooked.
Avoid Making Everything a Competition
Twin milestones can easily become a scoreboard, especially when relatives or friends ask the same questions repeatedly.
“Which one talked first?”
“Who’s walking already?”
“Which twin is more independent?”
You may not be able to stop people from comparing your children, but you can choose how you respond.
If someone comments that one twin is ahead of the other, you can acknowledge the milestone without making the comparison the focus.
For example, you might say, “They’re learning different things at the moment. He’s really interested in climbing, and she’s been working on her language.”
If a family member repeatedly labels one twin as the clever one or the baby, gently redirect the conversation. You don’t need to give a lecture. A simple reminder that both children have their own strengths can be enough.
Try to avoid making one twin the example the other should follow. Statements such as “Look at your sister; she can do it” might seem like encouragement, but they can create unnecessary pressure and resentment.
Instead, compare each child with their own previous efforts. You might say, “You tried putting your shoes on by yourself today,” or “You used a new word to tell me what you wanted.”
This teaches children that learning is about progress, not beating somebody else.
What If One Twin Seems Ahead in Everything?
Sometimes the differences seem to go beyond one or two milestones. One twin may be more verbal, physically confident, independent, and socially outgoing, while the other seems to need extra help across several areas.
That can be worrying, particularly when the difference appears to be growing rather than narrowing.
Try to separate what you observe from the conclusions you might be tempted to draw.
You might notice that one child follows instructions more easily, uses more words, and manages certain everyday tasks independently. Those are useful observations to share with a healthcare professional. But they don’t automatically tell you why the children differ or whether the less advanced twin has a developmental delay.
Write down specific examples if it helps. What can your child do? What seems difficult? When did you first notice the difference? Have you seen progress, or has a skill disappeared?
Specific observations are more useful than general descriptions such as “He’s behind his sister.”
If you have concerns about speech, movement, social communication, hearing, understanding, or other areas of development, discuss them with your child’s healthcare provider. Ask whether developmental screening or further assessment would be appropriate.
You don’t need to wait until the difference becomes dramatic. Early assessment can help identify whether additional support would be beneficial.
And remember that a developmental assessment isn’t a verdict on your child or your parenting. It’s a way to understand their needs and find the right support.
What If the Twin Who Is Ahead Starts Getting Frustrated?
Developmental differences can affect both children.
The twin who has mastered a skill may become impatient when their sibling can’t keep up. They might grab a toy because their brother or sister takes too long, answer questions on their behalf, or insist on doing everything themselves.
Meanwhile, the twin who needs more time may become frustrated when their sibling interrupts or takes over.
You can support both children without expecting either to change who they are.
Teach simple phrases such as “Let me try,” “Help, please,” and “It’s my turn.” Give the child who needs more time a chance to attempt tasks independently, and help the more confident twin learn to wait.
If one child is frustrated because their sibling can’t play in exactly the same way, offer activities they can enjoy together without requiring identical abilities. Building with blocks, playing with water under supervision, looking at books, or doing simple pretend play can allow each child to participate at their own level.
They don’t need to perform the same actions to enjoy being together.
It’s also okay for your twins to have separate activities. If one is ready for a more challenging puzzle while the other enjoys simpler toys, you can provide both without turning it into a statement about ability.
The aim isn’t to make every experience identical. It’s to give each child a chance to participate, learn, and enjoy their own interests.
Remember That Strengths Don’t Always Look the Same
When we think about development, it’s easy to focus on obvious milestones: walking, talking, counting, dressing independently, or mastering a new physical skill.
But children have many different strengths, and not all of them are easy to measure.
One twin may be particularly curious about how things work. The other may be attentive to people’s feelings. One may love experimenting with new activities, while the other notices details that everyone else misses.
These observations don’t replace developmental milestones or professional assessments when concerns arise. They simply remind us that a child is much more than the skills they have mastered at a particular age.
Try to notice what each twin enjoys, what makes them curious, and what helps them feel confident. Offer opportunities for both children to explore their interests without expecting them to develop the same talents.
You might have one budding climber and one future storyteller. Or you might discover that their interests change completely six months from now.
You don’t need to decide who they are going to be while they’re still learning how to use a spoon without launching food across the kitchen.
Let them surprise you.
These differences can show up in everyday situations, too. For example, one twin might happily eat whatever is served while the other rejects foods they ate without a problem last week. Feeding differences don’t automatically indicate a developmental issue, but they are another reminder that siblings can have very different needs and preferences. If mealtimes have become a challenge, take a look at One Twin Is a Picky Eater for ideas to help.
Taking Care of Your Own Worries
It’s one thing to know intellectually that every child develops at their own pace. It’s another to watch your twins every day and wonder whether you’re missing something important.
You may feel proud of one child’s progress and guilty that the other is finding things harder. You might worry that giving extra attention to one twin means neglecting the other. Or you may find yourself comparing them even when you know you don’t want to.
Those feelings don’t make you a bad parent. They reflect how much you care about both children.
When worry creeps in, try to focus on what you can do rather than repeatedly comparing milestones. Notice your child’s progress, provide opportunities to learn, and seek professional guidance when something concerns you.
You don’t have to choose between accepting your child as they are and getting them help. You can do both.
You can celebrate a twin’s current abilities while supporting the other through a challenge. You can recognize that your children are different without deciding that one is better, smarter, or more capable than the other.
And you can ask for help without feeling that you’ve failed to give your children everything they need.
Parenting twins involves making countless decisions with limited time and energy. You don’t need to turn their development into another competition you’re responsible for managing.
Helping Your Twins Grow Into Themselves
Handling developmental gaps between twins isn’t about eliminating every difference. It’s about making sure each child has the opportunity to develop, feel valued, and receive support when they need it.
Resist the temptation to define one twin by what they can do and the other by what they can’t. Notice their individual progress, give them opportunities to learn, and avoid comparing their abilities in front of them.
If you have concerns about a developmental delay, trust yourself enough to ask questions and seek an assessment. You don’t need to dismiss your concerns just because your children are twins or because someone tells you that one will eventually catch up.
At the same time, remember that a difference between siblings isn’t automatically a problem that needs to be fixed.
Your twins share a birthday, but they’re not following the same personal timeline. They can learn at different speeds, develop different strengths, and need different kinds of support while still growing up side by side.
You don’t have to make their journeys identical. You just have to help each child along their own.
