I've been trying to remove dairy from my diet. It's been a slow, but positive shift, though I don't think I'll ever get there entirely with eliminating cheese. I just can't quit you! I'm not a doctor and I'm not going to tell you what to serve your children, because you know they're not going to be happy about most of it anyway. You want some Vitamin D? Get a few minutes of sunlight outside each day and move that body around. Got calcium? Eat dark leafy vegetables, salmon and sardines. For me, I'm avoiding dairy because of the hormones and pesticides that are often found in homogenized and pasteurized milk. Even finding raw milk doesn't solve all the problems.
