Uh-oh.
Honestly, I think we should all brace ourselves. Super Nanny sometimes put the parents in a bad light. I remember seeing one clip on YouTube, a mother was lamented for making her son take in liquid soap for cursing. Liquid soap can be harmful and toxic to children. Well, even soap bars can be harmful with the chemicals they put in them these days.
I just hope it will be a positive experience for the deaf family.
