My son just turned 2 on the 3rd of Oct. And getting him to want to go potty in the potty has been such a pain. He knows whenever he goes in his diaper. He runs and says "Momma diaper wet/dirty, change me". But I'll ask him if he needs to go potty he yells "No Momma no potty" and will cry when I set him up there. He has gone a few times. but I just don't how to get him excited to want to go in the big boy potty. Your advice would be greatly appreciated.
