It's not working....

So I am starting to potty train Jackson, almost 2 1/2, which is proving to be a lot more difficult than Gabby who was potty trained at just before 2! Anyway, he sits on the potty every night before we get in the bath tub. Well the other night he is sitting on the potty and he looks down and grabs his man part and says - "it's not working mom". With that he jumps down and flushes the toilet. Well I thought that was so funny and just started laughing! BIG MISTAKE. Now every time he sits on the potty he announces that is not work and gets right back off! I have a feeling this is going to be a very long process!!!!!
