This is a tricky one isn't it?  Sounds like it might be a power struggle to me, and that you have tried different types of reward systems.  Sometimes children can regress when there are changes in their lives.  I wonder if anything else has happened recently?

You might have to pull out the big guns here and maybe you could give him some money (you decide how much) every time he uses the potty and buy him something really special.  Put it in a jar so he can see it growing.

You'll have to find out if there is something that he really wants, you could look through a catalogue together and choose, or do up his room etc. He is old enough to understand the concept and i found toys really worked for my son.....you will have to find out his 'currency'.

Another thought is, is he still using a potty?, maybe he is ready for the big toilet.  There are little padded insert seats that you can buy which fit over the adult seat.  My kids never used the potty and went straight to the big toilet with the little seat and a small step stool thingy so they could get up by themselves. 

Hope this helps.  Julie

Hi there. I just want to share with you what I've done, maybe you can get some ideas from it. My son is 2 1/2 years old and has only recently been potty trained.  At first I used a train sticker chart (I got free online). My son loves trains, so it worked. I told him that every time he goes potty, I will give him a sticker. And he then sticks it on the chart himself.

But then I switched to a star chart I saw on amazon.com. It has a place for a star for  just trying to potty, peeing, pooping, washing hands and flushing. So for just one trip to the bathroom, he gets several stars. And when he has about 15 stars on the chart, I told him that he can buy something from "mommy's store". I went to a dollar store and bought a bunch of things that I think he'd find interesting. I told him to get all his stars and give them to me and he can pick 1 item from my store.  He found that very interesting.

Good luck!

Did he have a uti infection, whilst potty training. May be he associates the potty or toilet with pain? Maybe putting him in pull ups and giving him a break from the idea for a while, maybe a month or two. Or if he communicates well but does not like nappies, you could negotiate that untill he pepees or poohs in the pot, he has to wear, nappies. However I would get his urine tested just incase he has a mild infection that is not symtomatic. If he has had a scare or fright on the pot you got, it may be worth taking him to choose a new one,that he has no bad association with, a clean slate as they say.

Good Luck Winnie.
