Hi E.,
I hope what I write below won't be offensive. I don't know you so I am only guessing at what's going on. I didn't know much about cooking and diet (I thought I was eating a good diet of foods before I changed what my family was eating.) So I am only guessing that you might need a little help in that area too.
I see you're trying to limit her fat intake with 1% milk.
One thing to remember is that fat is important for the body, especially the brain. You want to have the good fats and not so much of the bad fats. So getting the low-fat milk is good. You just want to be sure to get the important fats found in ocean fish, canola oil, flaxseed oil (don't use in a fry pan),...
You mostly have to be careful about sugar. Seeing that she only wants strawberry flavored milk, I'm guessing you might be giving her something like Nesquik or a flavored syrup. If you look at the label, you'll find sugar and you'll probably find high fructose corn syrup if it's a strawberry flavored syrup. If she's asking for milk A LOT and it has to have strawberry flavoriong, she's probably getting A LOT of sugar. Hence, she's probably gaining a lot of weight. High fructose corn syrup is the sugar that the body converts to fat the quickest. Read the labels on food you purchase.
I'm concerned too about how thirsty she is. I wonder if she is substituting the strawberry flavored milk for food. Why is her stomach so empty that she can be downing so much milk? Is she eating a lot of pasta? Pasta has a lot of complex sugars that break down into simple sugars in the intestines. Lots of sugar puts a strain on her insulin levels. A person gets hungry faster after having carbohydrates than after having protein.
Since I'm not a dietician, I would suggest you go to one to learn about what she is eating, what she should be eating, and what will keep her full longer - protein. Protein packs more energy than sugar and it does not disrupt the insulin levels, as far as I know - I can't imagine how it could.
As for strawberry flavored milk, I'd use real straberries if you aren't already doing that. More nutrition as opposed to the flavored sugar varieties which are also full of artificial colors.
Good luck!
