Have you tried to put a little chocolate syrup in the milk for him to try? Some children will drink milk with chocolate in it but will not accept it plain. Does he eat ice cream, yogurt, fortified orange juice, or puddings daily which are calcium sources to help his growing bones. Suggest having complete blood work to see if there any decrease of vitamins or minerals. In the meantime suggest a daily children chewable multi-vitamin.
He will drink milk but has recently stopped drinking as much and prefers to have no cheese or butter on things. I did start him on flinstones with iron. but there isnt a lot of calcium. I will try a supplement of calcium. His hair has softened since the flinstones addition it was brittle and difficult to comb. I will take him for bloodwork. Thanks so much I know it is a lot of work to keep up with us crazy moms!!! Paula
