Hi, I can use some advice. I returned to work this week. My son who is nearly 3 months old started daycare. Because he is breastfed I estimated that he would need about 3 to 3.5 ounces per feeding and he eats 4x a day at daycare. I pumped almost 10 ounces at work. then the daycare said that I did not leave enough milk. Baby was really upset and fussy afterwards. They asked me to try filling the bottles to 4 ounces each. I did, and they said that he was perfectly content after each feeding. Today I pumped less then 10 ounces at work. I am not pumping enough outside of work hours to make up for the shortage and be able to feed him at home. tomorrow I have to resort to using formula for 1 of the feedings. I am not sure what other options I have. I guess I am just one of those people who needs to supplement with formula? I don't have a huge freezer stash either. Any advice?
