Cod - I followed your advice in your last potty training boot camp and it worked brilliantly well.
About 5 weeks ago I took dd (2.5) out shopping and we bought knickers, special pooing and weeing biscuits, special wipes etc. Stopped using nappies that day and explained how she needed to use her potty if she wore knickers etc, etc and that she would get an animal biscuit if she did a wee and a chocolate biscuit if she did a poo in the loo or potty. We had two accidents (just wee) in the first two days and no accidents since. She is also dry in the night the majority of the time and wakes up and asks to use the loo.
So a very big thank you to you Cod for excellent and invaluable advice and giving me potty training confidence.
