Hi Lissie. I'm hardly a full-blown success story, but we're going through it at the moment.
A few weeks back, I decided to stop procrastinating with DS2 too; he wasn't keen on the idea, so I just told him that the next day, he would no longer be wearing nappies during the day, as he was now a big boy.
I stayed in for first couple of days, just putting him on the potty every 15 mins. Also kept a diary like this:
Time Potty Accident
After a couple of days, we had more ticks in the potty column than the accident column.
He has since learnt a degree of bladder control - whereas at first he was weeing every 10 mins, he can now go 2-3 hours.
He's been in pants ever since, and I can take him out and about (just make sure he wees before we go, and whenever there's a suitable time).
Only downside, is that he hasn't been asking to go - apart from when he's just started - and then been able to stop himself, with a "oh no, I just weed in my pants".... so I can hardly say he IS potty trained yet. However, yesterday he told us on 2 occasions that he needed the potty, so things are looking up!
Phew... HTH - and didn't bore the pants off you!!!
