I have had great luck potty training my 20 month old. Though its mostly on her becuse she hates being messy or wet. Recently I have been baby sitting my cousins kids. She has 2 almost 3 year old that is ready for potty training but nothing she tries seems to work. Giving her daughter a m&m dosent work becuse they are giving her the candy when ever she wants it not just when she goes potty. So they have asked me to help and im not sure how though i would really like to help out. My experianc with my daughter has been really easy for about 2 weeks she got a peice of candy after going potty an seeing how see doesnt like sweets that much she no longer wanted the candy and just wanted to go potty and be praised. So any tips or things that have helped you.I should also say that she will use the potty if left without a dipar or pants on and is asked ever couple of min if she has to go.
I think that all children want praise and encouragement from us, rather than a "prize". Kids are ready to start using the potty at different ages. So, when the child gets ready, they will work harder at it.
Some of the things that I found to help...take the child straight to the potty as soon as they wake up,don't give them anything to drink before they go to sleep at night, Praise the child, saying "you're a big girl!" (boy), clap when they use the potty and make sure that you do ask often because they do tend to forget especially if they are busy playing or doing something they really enjoy.
Make sure to put them in something besides a diaper, nobody likes to clean up mistakes, but if they feel how uncomfortable it is to wet themselves, then they might be more likely to go to the potty instead of the floor. If she is really having trouble, maybe a book about using the potty will help.
Hope these help!
