T.W.
I too bought a potty chair and used it only twice. It is too messy to clean and became is sang and stuff, became more of a toy than a potty to him. We went right to the big potty. When he was too short to stand at it himself, he would sit. If we were in public, I would have him stand on my feet and I would hold him a little higher. Honestly we attempted potty training a few times and he just wasn't ready. When he was, it happened in one day. So I say if it is taking more than a few days, back off a little and try again in another month or so.
