Potty Training...

Nowadays when it comes to potty training they have movies, books, and all sorts of potties from the musical to the sticker giving, and even a dance. I remember back in the day when it went from diapers to extra thick underwear and that was it. Now potty training has all of these whistles and bells that I really don't know if they are necessary. It has taken a few months for me to realize that the pullups we were buying for my daughter were enabling her to be comfortable still going in her pants. Last week we switched her to underpants to see how she would do and she had one accident and has since been going on the potty without a problem with the exception of nap and bedtime when we put her back in pullups. Now don't get me wrong I think some things are useful like the potty seat so that she doesn't fall in when getting on the potty and even some of the potty books to help explain why things change from going whenever wherever to going on the potty, but I really do believe that the musical potties and sticker ones and talking ones take it to a place that potty training just doesn't need to go. What do you find useful while potty training your little one? What do you think about all of the tools for potty training?
