When my daughter was 3yrs old we took the pacifier from her, she is now 4. Here's my concern I have noticed (not recently but since the pacifier was taken) that she still sucks either on her tongue or the roof of her mouth (but i think it's her tongue). it sounds just like she's sucking on a pacifier. She only does it when she is sleepy. Has anyone had their child pick up some strange habits once the pacifier was taken?
