What is best way to stop a 15 months old from sucking his thumb?

Question

luke, what is this thing called and where can i get it. give name of store,

Answer 1

what do you do to pacify yourself?  think about that.  let her/him have his thumb until he/she gets to an age where he might be teased.  why would you want to take something away from him/her that calms and sooths him/her?  

Answer 2

give him a pacifier. and make sure he always uses that

Answer 3

At 15 months he should not have a pacifier. Gentle positive reinforcement. Every time he puts his thumb in his mouth distract and gently take it out of his mouth. Distraction every time. If there is a particular food he does not like spread that on his finger while he is sleeping. I do not mean hot pepper or anything atrocious like that.

Answer 4
