T.K.
We used a Spiderman adapter. We put a step stool next to the toilet. I liked the idea of training him on the real pot, rather than something he might try to pick up and carry around. That way it's less of a change later when it's time to transition to the next stage. The one i bought was $12 at Walmart. Very comfy. I had him lean over the toilt and hold the lid. That aims them automatically.
