so DS is nearly 6, but he's still a sucker and it's disgusting! He sits there with his hands in his mouth sucking, he sucks the collars of his shirts, he sucks the string and ball thing on his hat, it's gross!! How do i stop it? I keep telling him 'get your hand out of your mouth!' 'get your shirt out of your mouth!' etc, and i've started threatening with buying him a dummy coz he sucks on things so much......is this something i should just leave or is it something i should stop? i personally think it's yuck, i don't mind toddlers having things in their mouths, but for a boy who's nearly 6, i don't think it's a good look
