My granddaughter is 5 1/2 yrs old. She has a movement disorder called Complex Motor Stereotypies and along with that is a sensitivity to loud noises. She will be going to kindergarten in a few weeks but still cannot go into a public bathroom because of the flushing, hand dryers, etc. She is extremely frightened by the sounds and has been since she was a baby. She refuses to go into a public bathroom. My daughter (her mom) is concerned about her going (or not going!) to the bathroom in kindergarten. It is also a huge problem when they are out and need to use the restroom. How should she handle this with my granddaughter?
