DS started trying cow's milk at 11 months and stopped probably due to an allergy at the time (seemed to give him a lot of gas, and he chose to stop). Since then he has been drinking diluted juice, and drinks only that since I have stopped breastfeeding him at 12 months.
However, we have had some recent success with a little milk. DH has started drinking milk exclusively when he gets home as his beverage of choice, and offers DS some from his plastic cup. DS likes "sharing" Daddy's drink, so he takes some. The only drawback is that Daddy drinks semi-skimmed (2%) rather than whole milk. Still, I figure getting DS to drink ANY milk is better than none! Since the success with him drinking sips of Daddy's milk, we offered him some in his own sippy, to which he accepted and will sometimes drink a whole cupful of his own, and now not only when Daddy is there, but sometimes for me in the day, too.
So for us, an example (Daddy drinking milk all the time) has worked really well. Gosh, they DO learn so much from our behaviour... :shock:
