So I'm currently working with my son Landen on potty training. He became really intrested in going pee in the toilet when I potty trained my Stepson 3 weeks ago. Landen has been using the toilet to go pee in for 3 weeks now!!! He is so excitied to be wearing his Big Boy Spiderman Underwear. Except we have a little problem ... He won't poop in the toilet. So once a day we have been having an accident.  With potty training the boys recieved a monster truck tattoos when they went in the toilet. I have even told Landen if he goes poop in the toilet he can get 2 Monster Truck Tattoos!! That hasn't been working So now every time he goes potty we put his tattoos in a cup and every time he has had an accident he loses a tattoo. So now we put them on at night. Everytime his Dad goes to the bathroom Landen goes with him and they sit on the toilet together but Landen still won't go. I am at a lost here ... Please help!!!
