Hi there
I decided to start potty training ds last sunday as he seemed to be ready, he is 2 and a half, he had got to the stage of telling me he had done a poo, and on and off would say he wanted a wee but whenever I tried him on the potty he wouldn't go, he did one wee on the potty the previous wednesday though so I thought I would give it a go anyway seeing as I would have a clear 10 days over xmas to dedicate myself to it without nursery interruptions.
After three accidents including two poos in his pants I decided I didn't have the energy to do it as I had come down with a stinking cold and needed to do the xmas shop. I did start in ernest again on Xmas Eve though as I knew I didn't have to go out anywhere. We had two accidents and 5 wees on the potty, I was asking him to go every 20 mins and every half an hour would make him sit on it for a few minutes. On Xmas day we had one accident and one poo on the potty. On Boxing day, one accident which was my fault as I moved his potty and didn't tell him Yesterday was a totally dry day and he started telling me when he needed a wee and he went a mammoth ten times including a poo, I think he had the novelty factor, plus I have made him a chart and every time he goes on the potty we put a sticker on it for him and a bigger sticker for every poo. Today he has taken himself to the loo every time (that's where his potty is) So all well and good I think he has cracked it, I must say I am amazed he has taken to it so quick, I just need to try him on the toilet now.
The trick is to start when you can spend the time with them, don't take them out if you can help it until they have the hang of it. It needs constant attention, the first few days you need to second guess them. I have found that dressing them in easy to pull down trousers is good too, because if they do have an accident they really don;t like the feeling of wet trousers, plus they also help to soak up the wee so you don;t get as much on the floor, just make sure you have plenty of clothes, I went to sainsburys and bought 4 pairs of cheap jogging bottoms and six pairs of pants to add to the 5 pairs I already had, eventually they will get fed up of being wet and getting changed all the time.
hth... good luck
