hi G.,
my 16 month old does the same thing, but wont TOUCH a sippy of any kind. there are a few things i do to help her, and she gets enough milk AND calcium for the day....
1. seeing she will drink from a straw (juicebox), try getting the baby cups with straws at wal mart instead of sippies.
2.continue offering milk, yogurt and cheese, even if she wont eat it. eventually she will. just keep offering it and dont make a big deal out of weather or not she eats it.if she gains that power over you, it will result in an even bigger eating problem down the road.
3. try to "sneak" milk/calcium into other foods prepared with milk (eggs, mac and cheese, etc.).again, just keep offering it to her, eventually she will eat it.
4. seeing she has a milk allergy, im not sure if she can have these or not, so you would want to check first, but my daughters favorite snack is gerbers graduates yogurt melts. you can get them in the baby food isle at the grocery store.
5. give her some tropicana oj with added calcium each morning with breakfast, and/or smoothies that include milk, yougurt, or ice cream, with her snacks.
by doing these things, my daughter now gets 24-30 oz of milk to drink each day, AND gets MORE than the recommended amount of calcium (milk, cheese, yogurt melts, tropicana oj, ice cream, pudding, etc.).
