Girls, hello! I've run out of milk completely, only giving her breast milk at night so she can fall asleep. She doesn't drink this, it's not scary if you give her homemade food, will it damage her stomach? I started breastfeeding her at four months old and she won't choose anything but homemade food. They just keep telling me that formula is definitely needed. ?
