Our 5 year old son, in the past week, has 'aquired' an attachment (sort of) to food that has us worried and at a loss on what to do. It started with popcorn at his schools Fall Festival - he put a piece into his mouth then proceeded to cry hysterically and say he missed the popcorn. He wouldn't eat anymore. It has progressed now to some of his past favorite foods chicken, green beans, oatmeal w/ anything in it, PBJ's, FRIES!!! etc. He will eat applesauce & yogurt and drink water & milk with no meltdowns. After one begged (me begging) piece of food he says he misses the food, asks me if I remember what it looks like and asks if I can draw it for him - all while crying hysterically. We asked his doctor and she has never heard of this issue - she had him eat M&M's in her office which he did so reluctantly but without a meltdown. In the car he asked if I could draw the M&M's and started crying. The only thing that had changed in his life was he was put on Singulair. I have stopped (as of 2 days) with the Singulair with no change in food issue. He has lost 4 lbs in 4 days and he is avg size. Before a week ago he would eat veggies, fruits and meats - he enjoyed eating. He is otherwise a happy (a bit of a jokester), smart child with no other issues physically or mentally - goes to Kindergarten, plays soccer, has stable home with Mom and Dad present. Could this be a control issue? Any advice would be so appreciated.
