i used a rather LOUD and ANNOYING potty that i bought at walmart. it had sensors at the bottom of the "pot" and every time it gets wet it sang a positive tune. DS sat on it every 2 minutes to see i think if i was still mentally sane
but have to say it did help get the job done. comes with a sticker chart so progress is noted, and he LOVED this part.
DS i might add started peeing in my coffee cup
: and this is how i knew that he was ready!!! also started this venture way before 2. i think it just really depends on the child and when their ready. my oldest DS wasn't done with diapers until he was almost 3. DS only wears a diaper for outtings (public toilets scare me) and for sleeping.
i tried the toilet seat insert with him as well, he was scared of it.... he also got his "pee pee" stuck underneath it trying to get on to it. that was the end of that....
i'm all for the loud singing toilet seat... he didn't need it after a week, and i also discovered that he was using it so that he didn't have to use the "big" toilet. i put it in the garage and that was that... he now informs me that he's pooping and come wipe his butt!!!
this toilet seat that i used has flashing stars on it... i can't remember the name. i know that it is a white and blue potty and this is my recomendation. hope everything works out for you!!!
