My 11 month old act like we don't feed him.... It's annoying

My 11 month old crys when he see food like he never eats and he eats more than your average 11 month old. He was eating full peanut butter and jelly sandwiches by the time he was 8 months, I know 2 year olds that don't eat a whole sandwich. He wakes up wars breakfast his dad gives him this big bowl of oatmeal and fruit I usually give him half of what his dad does because I feel like he over feed him. I might give him a waffle with peanut butter on it and some fruit not the side and a couple oz of juice. He snacks all day basically in between meals yet when he see someone eating he cry for it and it's really embarrassing. Idk what to do.
