Hello! I highly recommend researching Weston A. Price's baby formulas. Are they a bit of work? Yes, it's not as convenient as opening a container of formula. But after the first week I had a system down. My milk started drying up from being pregnant, and up to that point my DS was exclusively breastfed. He handled the WAP goat milk formula beautifully! I love that I was able to give him something from a farm and not a factory. It's pretty controversial, most things that go against the grain are, so do your research. I know western medicine docs would probably prefer formula, but my gut said do what my ancestors would do. If you don't have all of the ingredients, don't stress, I know the list looks long.
