how are/did you transition from formula to whole milk? my daughter is 1 years old and I have been adding whole milk to her bottles for about 2-3 weeks now. She sometimes will only take a few drinks and I have to keep giving her the bottle. there's other times she'll just drink straight whole milk (about 2 oz). I have 2 cans of formula left, once I'm out it's just going to be whole milk. I'm nervous as to how she'll take it. Do you warm your lo's whole milk bottles? How do you do it when leaving the house (making bottles) ?
