It's been known to injure and wear the inside of the child's mouth if done too much. The teeth can start to get displaced, and the thumb can get blisters and calluses from sucking too much. Also, as a social statement, you wouldn't want your kid to be in highschool and still be sucking his thumb, right?
It will screw up the natural position of the teeth. It will knock the teeth out of the roper alignment which will lead to an overbite . This will have to be corrected by an orthodontist, using braces.
And orthodontists are not cheap!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
