He may be too young to understand the enitre process... I prefer to wait until boys are older than 2.5 to start training because of their maturity level. My oldest is 5.5 and he was not trained until 4 and my middle son just turned 4 and he was trained at 3.5 my youngest just turned 2 and I wont start trying until 3 unless he decides to do it on his own...
Good luck
