Hi! First of all, these forums are a fantastic resource and I am so grateful to have found this community.
I have returned to work full time and my 14-wk-old son spends his days with his nanny. He is gaining beautifully (measured 14 lbs 10.5 oz on 2/13). He eats 7-8 times a day, breastmilk only. While with his nanny (8 am to 6:30pm), he gets three bottles. I used the kellymom calculator to determine that there should be about 4 ounces per bottle. My nanny disagrees and wants bigger bottles, because he cries briefly after each feeding. I think he cries because the feeding is over too quickly. He is otherwise happy with her: naps and does tummy time, focuses on books, toys, etc.
Things got more complicated on Friday when the pediatrician said that the rule for bottles is the age of the child in months+ 1, i.e. he can have 5 ounces when he is 4 months old, 6 ounces when he is 5 mo, etc. I am sure he will love that, but where is the milk going to come from?!
My current pumping capacity is about 15 ounces per day. I really don't know how to get him bigger bottles...
