weaning a 1 year old

I would definetly speak to your pediatrician. While there are other sources of calcium, milk, especially whole milk, is an important source of calcium, healthy fat, and vitamins. You want to be sure your little one is getting the right amount of nutrients, and your pediatrician should be able to help you figure out the best way to do that.

Milk isn't neccessary anymore for your one year old. There are other ways to get your 1yr old to get dairy...yogurt, cheese, ice cream. I wouldn't worry about it, there are a lot of people who do not like milk or who are lactose intolerant and they are quite healthy. You can talk to your pediatrician about dairy alternatives if you still have some concerns.

Maybe flavor it with a little chocolate syrup or strawberry flavor? Not too much though. Try those drinks for children that claim to give them full nutrition. Also, maybe see the doctor?
