Query: ONLY Thing that Worked for My Son

I was so frustrated trying to potty train my son and he show NO interest before this video. It peaked his interest and after watching it 40 times in 4 days he sat on the potty. After 5 days he went for the first time. Now just 8 weeks later he is fully potty trained but still loves the video. My daughter likes it too (she's 1) but during a certain part she cries because she doesn't like one of the characters.Good Luck to you all, hope you are diaper free soon!Amanda
