DS has resorted to holding food in his mouth for long periods, even his favorite foods that he chooses to put in his mouth. Eventually he spits it out somewhere. I have encouraged him to do this step into the garbage. I cannot get the kid to swallow!! This happens several times a day at snacks and meals.
He also often holds saliva in his mouth, walking around with his lips puckered, he is doing it on purpose. But WHY??
He has not gotten 2-yr molars, could it be related? Is this a normal thing for toddlers to do?
