Yes, TouchPoints™ can be used in this type of situation. In one case a 10 year old boy who functions but at an 18month to 2-year-old level, is nonverbal and also has C.P. and a seizure disorder found some help with TouchPoints™.
TouchPoints™ do have small parts that could cause a choking hazard so please pay extra attention to children.
Most parents with children with developmental disabilities also find TouchPoints™ to be helpful for themselves because of the additional stress of parenting so if your child does not end up using them they still might be a good tool for any family.
