My son is going to be 5 in June and he's only 35 lbs. he's tall and looks so skinny. He is so slow when it comes to eating, and it is very frustrating for me. He can sit at the table for over an hour and not eat. Most times I have to end up feeding him because we need to get somewhere or do bedtime or whatever. Does anyone have any tips on how to get him to eat faster or put on more weight? I don't want to stuff him with food and I can accept that he's just thin but he doesn't have much energy either. He wants to be carried after he comes home from school, and gets so tired sometimes after walking for a short time.
