This may be a bit off topic, however it affects many families. We have a four year old with autism we are trying to potty train and a soon to be 3 year old with ADHD who isn’t trained yet. They both disrobe and play in their diapers.
We actually invented some special needs autism clothing that helps the situation. It is an escape proof pajama called The Wonder Jumper and it is a romper/sleeper that zips in the back. Thanks a lot!
