My 5 week old has been sleeping 3-4 hour stretches and waking to nurse for only 5-10 minutes on one side at night. Is this going to affect my supply? During the day she nurses every 1.5-2 hours. Do I need to pump at night to keep the supply up or pump more during the day to average out to 10-12 sessions. When I pump at night I can get 1 oz from each side in under 10 minutes after 2-3 hit gap so she is getting about an oz from the one side and then dozing off. Is this normal and ok? Her weight gain is fine, about an oz a day and she has lots of wet and dirty diapers.
