DS is 21 months and still puts everything in his mouth, not little pieces like legos or marbles, it seems like he likes to hold toys and gnaw on them. He’ll lick mirrors, the doors, his high chair. The other day we were at the pediatrician and he licked the exam table and the floor. THE FLOOR! He’s not teething, he’s always been like this. Any ideas on how to stop it? I try redirect him but if I took away every toy he put in his mouth he wouldn’t have anything to play with.
