D.P.
My daughter does the same. She's 2 and has been in daycare since about 3 months old. When she started in the one's room she stopped eating as much dinner at home. I used to worry, but then I relaxed as long as they said she ate everything there all day. And some days she did eat dinner and eat more than me. For the most part now she eats dinner, but some days she doesn't. I think a lot has to do with how they feel. If they are tired or sick or too excited they won't really eat, but I also have talked to doctors and read things and found it really is ok if one meal is skipped as long as they ate the others. He'll be fine and still grow like a weed. :o)
