My husband and I are on opposite sides about some of this (I won't say who believes what, haha!) and wanted to see what HB thought!

There are so many "rules" about bottle feeding, whether it's breastmilk or formula. Do you follow them? Like, formula has to be discarded within an hour? If your LO starts a bottle and doesn't finish, do you throw it out? Save it? Would you re-heat a bottle?

Etc etc... share what bottle feeding rules you follow and which you are "meh" about!
