I use a sticker chart when potty training. No treats here at all! I start them out sitting on the potty every half hour or so...if they actually go then they get a sticker on their chart. No rewards for just sitting there. After 1 day of every half hour, I increase the time every day until they can go a couple hours without going. My kids have been potty trained day and night within 5 days using this method BUT they have to be ready. I don't start helping with potty training here until the child can fully communicate with me and tell me when they have to go or they are tell tail signs of it...ex. holding themselves, etc. If you try potty training before they're ready then it's you and the parents that are trained NOT the child. The child needs to be able to recognise their body's feelings and signs of having to go. I also don't allow underwear until they can go 2 weeks accident free. They can wear training pants with plastic pants over top or pull-ups but I personally hate pull-ups...they're a glorified diaper.
