So my son is years old and has SPD and at first didn't really say words, but now he has begun to speak a few words. I feel like he understands a lot but of course not everything. He is liking to take his pants and diaper off at nap and bed and wakes up with no diaper on, and having peed in his crib, so I am wondering if these are indications he may be ready. However I have tried putting him on the potty and he just stands right up. I don't think he quite gets what I want him to do. Because he isn't speaking much yet I don't really know how to go about potty training him. Does anyone have any suggestions that have worked for them. TIA.
