A tactile undersensitive child needs a lot of input to get the touch information he needs and often seeks it out on his own, often in unsafe ways. A tactile defensive child needs to be desensitized so he can more readily accept touch experiences. This can be tricky, because as a parent, you want to accommodate your child by helping him to avoid threatening experiences to make life easier and at the same time, build up his tolerance for inevitable unpleasant experiences as well.
