Oh dear, maybe you are asking the wrong person! My son was dry at 2 yrs 10m but has only got the poo bit sorted now that he 3 yrs 3m! Everyone else's children seemed to have the lot sorted at about 2 and I thought I must be doing it all wrong.
He NEVER told me when he needed to do a poo, always did it in his pants secretly or waited for his night time nappy. I thought he would never get it right as he just didn't seem to care and would deny it to the end. However, I made a lovely star chart featuring a fire engine (his obsession) with a tall ladder on it. It had a moveable fireman on it who was going to climb up a rung every time ds did a poo in his potty. At the top was a cat to rescue. Also at the top (key point coming up) was a packet of milky buttons (I never buy him sweets so this was a real treat) The idea was that he got one for trying to do a poo on the potty, two if he actually did something. He also got to put a sticker on each rung.
I thought I had it sorted but that poor fireman went NOWHERE for weeks and weeks! If ds did it in his pants I would say, 'oh that's sad, the fireman isn't going to get the cat in time and you're not going to get any chocolate' and one day, I managed to get him on the potty in time when I could see he needed to and we 'caught' it and had a big ritual of fireman, sticker, chocolate. Even after that it was slow progress but two weeks ago, it just seemed to click with him and I heard the wonderful words, 'mummy, I need to do a poo' and he hasn't had an accident since even though he has had diarrhoea for three days!
Sorry that is so long winded but dh is doing bath time and I am making the most of the chance to type unaided by my sons!! Anyway, perhaps a themed star chart of something they like might work but at the end of the day, I just had to wait until ds was ready and try not to get cross in the meantime.
I hope that is not entirely useless to you. There is another thread somewhere about this (perhaps I started it myself) but I can't remember which one it is. If I find it I will tell you here.
