I just got a job offer and am going back to work in a little over a week (eek!) and need to figure out how to feed LO while she is with the nanny/daycare. I have no idea how much she eats/needs.

LO is 7.5 months and has been mostly EBF on demand. She eats every 3-4 hours during the day. On the rare occasion that DH gives her a bottle, she takes it easily, but eats anywhere between 2-5 oz and it typically takes me 2 pumping sessions (after feeding LO) to get 4-5 oz. I usually feed her when she wakes up between 4-6 am, and I will be gone from 6:30 to 5:15 every day, so 3-4 feedings per day? We also do solids twice per day.

I know I will probably get more from a pumping session if I don't feed her immediately before, but how much do I need? How much did/does your 7 month old eat and how many pumping sessions did you need to get that?
