At 12 months we started transitioning our LO from bottle to sippy cup and breastmilk to whole milk at the same time. She was doing fine with bm/whole milk mix. Now that my stash is gone, we started giving her whole milk and she is refusing it. She does drinks water from sippy but just not milk. I don't know if she's getting enough nutrition if she doesn't drink any. It's like a constant battle to get her to drink just one ounce. Should I try other types of milk?
