Hi, my son just turned two and refuses to sit in his high chair. We converted the top part of his high chair to a booster seat and that worked for maybe a week, but now he refuses to sit in that to eat as well. We started letting him sit at a "grown up chair" at the table but he keeps getting out of his chair in the middle of meals and trying to grab everything he can from the table. We started trying to have him eat at a kids table but he won't sit still and keeps getting up and then climbing on the kids table or runs around the room and then it takes him forever to eat (if he does decide to eat his food). We have tried putting him on timeout when he gets out of his seat or throws food on the ground but it doesn't seem to be helping. What do we do now?
