Convincing DS to eat cold solids?

missfire

DS is really picky about his foods and will refuse to eat anything cold or room temperature. Recently I discovered that he'll eat them pretty well if I microwave them, but even then, I have to heat them up 2 or 3 times in the course of his meal, because once they get room temp, he won't touch them. But at daycare, they don't have a microwave in the infant room, and can't heat up his food.

Have your babies refused cold food, and do they grow out of it? Can I "encourage" him somehow?
