Your baby may want to nurse a lot at first. That' s normal. Her stomach is small and can't hold a lot. If she needs to suck but is not hungry, give her a pacifier. Do not give her a bottle until she has been nursing well for about four weeks.
Some babies sleep for several hours at a time during the day.
This makes it hard for the baby to eat enough to grow. It also may mean the baby wakes up more at night to eat. When she does, pick her up and change her diaper. Don't wait for her to cry. Breastfeed her on both breasts and talk to her while she nurses.
