I saw an episode once with one of the children who was autistic. Joe did tell the mom she had to interact with him each and every day.
I do think if Jo and crew came to my house, they would get one look at N*'s room, and call up thank you Pennington and the Extreme Makeover People and tell them to get over here quick!
Someday, she'll move out, and THEN I'll do the remodelling I've been putting off for 8 years!
