DS has been exclusively breastfed for almost 9 months now, but I think I'll be sending formula for some or all of his 3 bottles at the sitter starting in the next month. (Pumping is taking it's toll on my time at work, I've had to dip into my small freezer stash over the last month, and DH is moving out of state for a job for the next 6 months, so I'll have more to do on my own.) I'm okay with giving formula, but I realize I have no clue where to start. Are there brands that breastfed babies prefer, in terms of taste? Do I use the standard infant formula or the 9-24 month one? Do I introduce it mixed with BM, or on it's own? Thanks for any advice. I'll be talking to the pedi next week at our 9 month visit, but thought I'd learn from your experience as well.
