well done on getting to 15 months! Ash weaned himself at 13.5 months and I was so upset. He would ask for it then he just didnt' want it. Have you tried not offering it and only feeding when she asks? That would be what I would try first. She is still too little to understand really. I've heard of people putting bandaids on their nipples and saying they are 'ouchies' so no more.

You don't have to offer cows milk at all. Ashton only has it in a bottle before bed, he drinks water the rest of the time. Cows milk isn't an essential part of a childs diet as long as they are getting calcium from vegies and other dairy like cheese or yogurt.

Good luck.
