My 13 months old has been a great feeder and has loved her milk. She went from breastfeeding to bottles with no bother but I've been trying her with cow's milk since she turned 1 and she is not having it. Tried it warm, cold, in a bottle, in a cup and she just spits it out. Someone suggested mixing some petit filous in it since she loves that but she has one sip and that's it. Tried different time of the day and doesn't seem to have much difference. Anyone else experienced this and any suggestions?
