He has very little to no appetite. Recently saw the pediatrician and although she didn't say she is concerned about the weight my intuition picked up on something wrong. She did ask if he eats and I told her he doesn't eat lunch often. He is very active but does complain often that his muscles ache after a hard play. I can see his ribs on his back. Being thin runs in my family and I have always been slim but he looks scary skinny to me. I try hard to get him to eat and even go old school with him by letting him sit until he finishes his food on his plate. Any comments would be appreciated. Anything
