My 10month is breastmilk fed but unfortunately we only may have a couple more days worth of breastmilk. She turns 11months on the 29TH. She doesn’t like baby food at all n will do finger food for like apples but most of the time she is only biting n not really eating. Would it be too soon to start cow’s milk or should we switch to formula. I am not against either one, I just want to make the best decision for her.
