I am wanting to begin to wean DD, she just turned the big ONE, and I have introduced cows milk to her. The first couple of times, she spit it out, now she doesn't spit it out, but takes 1-2 sips and thats it. She does drink water out of her sippy. I can't get her to drink ebm/cows milk out of her sippy. When I am away at work, she takes a bottle from DH with ebm in it, he tries the sippy, but she won't take it. Is there a trick to getting her to accept the sippy cup with milk in it??
