A.P.
My son will turn 1 Jan 30 and also is EBF, not even bottles. Just got the hang of water in a sippy cup. I think it will just take time and alot of offering to get used to another form of milk. Funny how they know, as different as human milk is to cow milk, that they refuse the cow milk.
Kids technically dont need milk, just the calcium and vitamin D. Milk just happens to be the easiest form of it. My friend gave her daughter, watered down enriched OJ, who at just over 2 still refuses milk. Cheese, yogurt and calcium rich veggies are also fine for servings of calcium. The pediatrician or nutritionist can guide you on getting enough nutrients but cow milk is not the be all end all.
