Some babies sleep much more than others. Some sleep for long periods, others in short bursts. Some soon sleep through the night, while some don't for a long time.
Your baby will have their own pattern of waking and sleeping, and it's unlikely to be the same as other babies you know.
It's also unlikely to fit in with your need for sleep. Try to sleep when your baby sleeps.
If you're breastfeeding, in the early weeks your baby is likely to doze off for short periods during a feed. Carry on feeding until you think your baby has finished or until they're fully asleep. This is a good opportunity to try to get a bit of rest yourself.
If you're not sleeping at the same time as your baby, don't worry about keeping the house silent while they sleep. It's good to get your baby used to sleeping through a certain amount of noise.
