My almost 4 year old girl has a HUGE appetite. I honestly mean it lol

She eats everything she sees . She weights 40lbs and last time her dr said she is in the 95th percentile and needs to watch her weight but I just cant . I serve her meals but I get together with family alot too so we usually have food around the house and she will eat everything she finds .

When I go party she will keep coming back for more n more n more . I tell her to stop and that she ate hers but no . She will say plz plz n take it n run . I feel embarrassed cuz everyone comments abt her eating alot n makes me feel bad that I cant do anything. She wont be full with one food. She has to have more. I have to always take all food away frm her or she will stay eatting lol 😔 any advice
