How old is she, emmielou? I tried to train dd at just gone 2 and she was able to wee and poo on the potty so long as she was bare-bottomed but the moment she had clothes on / we were out etc. she'd have accidents. She also wasn't that good at telling me when she needed to go, so much as going when I suggested it. So I postponed for a while and have just now been training her again at 2 1/2 and she's been in knickers only for a couple of days, then clothes since and only had accidents really for a day or so. From what I've heard / read, it's important to get them into underwear / clothes so they really learn the difference between wet and dry.
my dd2 has been running in from the garden yelling 'wee wee' and sitting on the potty. she is still bare bummed, and i gave her a week off due to dh being taken back to hospital, but am determine to crack this quickly. we had 3 accidents this morning, but none this afternoon.
