Catnapping Baby (Short Naps): Causes & Fixes | Parenting Hub
30–45 minute catnaps are biologically normal in young babies. Here's why, when to expect change, and what actually helps.
Catnaps — short 30–45 minute naps — are the most-Googled baby sleep problem and one of the most biologically normal. Here's what's actually going on.
Why one sleep cycle is ~45 minutes
A baby sleep cycle is about 30–50 minutes. Between cycles is a brief light-sleep moment where baby half-wakes. If they don't yet know how to link cycles, they wake fully — hence the 45-minute nap.
What helps
- Good sleep environment: dark, ~19–22°C, white noise
- Match the wake window to age (see our wake windows article)
- Quiet wind-down before each nap, not just bedtime
- Try a 'rescue' resettle: at 30–35 min, hand on chest/shush for 5–10 min
- Last resort for very short days: contact nap once a day to top up
When to wait it out
Most babies start linking cycles between 5–8 months as sleep matures. Catnapping by itself, in a happy and growing baby, is not something you need to fix.
When to seek help
- Total sleep <10 hours per 24 hours consistently
- Catnapping + poor feeding or weight
- Baby always inconsolable on waking — discuss with GP
Common questions
Is the pram or carrier nap bad?
No. Movement naps are normal and often longer. They don't 'spoil' cot sleep.
