My question is how do I get him to put on weight? He does not eat anything but spaghetti, chicken patty sandwiches (plain), hamburger
helper (1 kind only), peanut butter & jelly sandwiches. He loves sweets. Cereal and chocolate. He snacks on cereal all day and night (no milk). I try to get him to eat more foods. He will eat a hamburger (plain). He does not like any condiments or sauces. He doesn't eat mayo, ketchup, mustard, ranch, etc.
