L.G.
He's hungry just now. Let him eat. Lots of babies put on weight before they grow. My grandson was a BIG eater and now he is nearly six feet tall. He was a rounder sort of child and very handsome. He's muscular, athletic, and very handsome.
Another grandson of mine eats and is rotund and at nine years of age stands at 59 inches.
Feed him really good food and he'll grow up straight tall and healthy.
