Is It Normal for One Twin to Sleep Worse?
Why twins rarely sleep the same — and what it means.
Yes, It’s Completely Normal
Most twin parents notice one baby sleeps better. Different sleep needs are common — even in the same womb.
Different Temperament
One twin may be more sensitive, alert, or easily overstimulated. These traits show up early and affect sleep.
Different Feeding Pattern
If one twin eats faster or takes bigger feeds, they naturally sleep longer. Small differences add up at night.
Birth Order + NICU History
The firstborn twin often regulates faster. Any NICU time or early challenges can impact sleep for weeks or months.
Sleep Maturity Isn’t Synchronized
Twins don’t hit sleep milestones at the same time. One may consolidate nights earlier — the other catches up later.
What You
Can
Do
Keep a simple routine. Respond to each twin’s needs individually. Avoid comparing — they’re two different babies.
