I just wanted to check when your babies / toddlers stopped putting things in their mouths? Mine is 15 months, the first 4 molars have come through, the last one about a few days ago, so I know he's uncomfortable as he puts his finger there but I am just curious as to when your toddlers stopped mouthing items. My nephew is 3 1/2 month older and he never really mouthed anything and had completely stopped by 14 months xx
