How long is a sleep cycle baby?

A baby's sleep cycle is much shorter than an adult's, starting around 40-60 minutes in newborns (half active/REM, half quiet/deep) and gradually lengthening to 60-90 minutes by 6 months, eventually reaching the 90-minute adult cycle by toddlerhood, with more deep sleep and less active sleep as they grow. These short cycles mean babies often wake between them, which is normal, especially in the first few months.
