That is a good sign that he is ready to start potty training! He may just want to copy you, but copying you intails using the potty too..not just sitting on it. My son (and i've read that most kids are this way) wanted to play with it for a long time. He would sit on it in the living room, etc. My son in particular never wanted to actually use the potty chair...he had to have the real thing (the kind that just sits on top of the regular toilet seat)...so I got him one..he played with that one too for a while. One day he went to the bathroom door and kept playing with the knob tryign to gt in...so I got him set up on the potty and he used it! The important thing is don't push it...don't force it in any way or it may delay the training. If it is fun and in his own time, he will do best. good luck! It's a lengthy process, but a rewarding one. Remember, lots of praise for a job well done (even for trying)!
