The amount babies sleep, even when they are very small, varies a lot. During the early weeks some babies sleep for most of the time between feeds. Others will be wide awake. As they grow older they begin to develop a pattern of waking and sleeping which changes as time goes by. Some babies need more sleep than others and at different times.
You’ll gradually begin to recognise when your baby is ready for sleep and is likely to settle. Some babies settle better after a warm bath. Most sleep after a good feed. A baby who wants to sleep isn’t likely to be disturbed by ordinary household noises, so there’s no need to keep your whole home quiet while your baby sleeps. It will help you if your baby can get used to sleeping through a certain amount of noise.
