  3. My Husband and I work on my step son sucking his thumb, but his mother allows it, We can see that his teeth are being affeced but she doesn't care. His top teeth are coming out and his bottem teeth are moving in. We tryed to tell her but she doesn't care. As soon as he sees her he puts his thumb in his mouth and she yells at us for telling him to take it out. We are lost on what to do.
