Meal plan

My son is a picky and fussy eater too . But I would eat with him on the same table to encourage him to eat more . My 17 months old takes about 8-10 spoons . But I let him have 3 meals a day and 2 snacks in between , with 4 feed of formula milk , plus water every now and then to make sure he is not dehydrated with our hot weather . He is not gaining any weight but he maintain the same weight now .
