My daughter never sleeps good when she has very much cows milk, we use 2% for our 3 and 5 yr olds. I give my 1 yr old soy milk and she likes it alot. My older son will drink it too, but the 3 yr old won't so we buy both. Dr said it was fine and had everything she needed it in, and it doesn't uspet her tummy like the cow's milk does. I heard that it might have a lot of hormones in it though, so I have gotten the Almond milk a couple of times and she likes that too, but I don't and doubt my other kids would like it.
