Mine goes through phases of hating yogurt and cheese. I don't worry too much about it because he loves milk and will gladly drink it all the live long day if I let him. I wouldn't worry too much about it until you've started whole milk. If you've got a milkaholic on your hands, he'll easily get enough calcium. If not, you might have to start looking for other sources of calcium, like you said. For the yogurt, have you tried mixing it with fruit or veggie puree? For now, keep trying...I've read that toddlers often have to be exposed to a new food 10-15 times before they'll even think of taking a bite!
