Does My Baby Sleep in the Womb?
Yes. Babies sleep for much of the time in the womb, cycling between active (REM) and quiet sleep. That is why you notice periods of movement and stillness — the quiet spells are often your baby sleeping.
Sleep cycles in the womb
Babies alternate between active sleep (with movements and REM) and quiet sleep. These cycles are usually short and repeat through the day and night.
Why you feel active and quiet periods
You will feel more movement during active phases and less during quiet sleep. Getting to know these patterns helps you recognise your baby's normal — and notice any change.
Frequently asked questions
How much do babies sleep in the womb?
A lot — babies spend much of the day and night in sleep cycles.
Are quiet periods just sleep?
Often yes, but a lasting drop in movement should still be checked promptly.
Does my sleep affect my baby's?
Babies have their own cycles, though some become active when you rest in the evening.
