I BF and pump for the nanny. Recently my almost 10 month old has only been taking 1-2 bottles while I'm gone at work. She's eating a LOT of solids though.
I BF her in the morning around 5/6 am and I would guess she's getting 5-6 oz at least
Then nanny gives her a 5 oz bottle around 10/11 a.m.
Then sometimes another bottle in the afternoon if she wants it so another 5 oz.
Then I get home and nurse her a little (not much) so maybe 3 oz?
Then at night she does nurse a lot to sleep so maybe another 5 oz?
So if I had to guess she probably takes in 20 oz a day apx. I'm thinking of dropping one pumping session at work because she's not as interested in the bottles during the day and I still BF her plenty at home, AND I have a lot of frozen milk.
