Will this program work with children?
The Correct My Tongue Thrust program requires that a child can focus on where their tongue is in their mouth and then change that by watching the video and/or you, the parent. You know your child better than anyone. I usually don't see them under the age of 7-8 because a certain level of maturity is needed to practice tongue exercises twice daily. This may only take 15-20 minutes. I have worked with a 4-year-old autistic child whose mother was great about ensuring her child was doing the exercises and doing them correctly. He was very successful with this program.
It won't hurt if you get the program before your child is ready. You can always pick one exercise from Lesson 1 and work on that for as long as you like. When your child is mature enough, both of you will be ready.
