Re: Nanny overfeeding the baby, not sure how to talk about i
since you like your nanny, i would probably address it by trying to appeal to her desire to help you out. you know? like, "it's so tough to pump enough, i love doing it, but those extra 2-3 oz she takes wehn she's with you compared to DH are really killing me. i'm doing everything i can, maybe there's something else you can do to stretch out the milk a little bit?"
ETA: change that last sentence to "Maybe there are some strategies we can work on together to stretch the milk out a little bit?"
those would include leaving smaller bottles, having her hold baby off in the last hour before you're home, that sort of thing. i agree with PP about smaller more frequent bottles.
