Well with Jacob he would crakc up and simply refused to pee in his nappy and we taught him how to take it off himself. not a good thing to do if they still wear them during the day though lol

if you can talk to him about wee's just say no more wees in the nappy ok.. Lets go to the toilet when the sun wakes up.. Or check his nappy as soon as he comes into your bed and if dry go straight to the toilet
