My baby is 6 months old and he has reverse cycled since I went back to work. I'm fine with nursing all night long but I'm completely empty in the morning and find it hard to pump enough while I'm at work to leave the nanny in the day. What is the bare minimum I can leave? He is fed by bottle at 9am (5OZ), 12 (6OZ), and 3pm (6OZ). I'm now breaking into my freezer stash as I am constantly about 3 ounces short each day. Does he need 17 ounces during the day if he's at the breast all night long?
