The more you feed your baby, the more milk your breasts will make. Let your baby guide you, and feed him whenever he wants.
If your baby is very sleepy, you may need to wake him and gently encourage him to feed more often. This will stimulate your breasts to make more milk.
Your baby may lose weight when he's weighed during his first few days. This is normal and usually doesn't mean he's not getting enough milk.
You may start to make less milk if you don't breastfeed often. For example, if your nipples are sore and feeding hurts, you might want to stop before your baby has finished. You may also make less milk if you try to set a routine, instead of feeding your baby when he wants it.
