Thank you for your reply. Doctor suggested putting her back into nappies or pull ips but i felt it would be a step backwards. Childminder has also refused to take her if i put her back in nappies!!!
If i could not send her then i wouldn't but i cannot get a decent amount of time off work. I have got a new reward chart and she is allowed to choose her treat if she manages all week with out messing herself so fingers crossed.
Has anything happened at nursery or something which may have triggered this behaviour off? Also compare whats she is like in different environments. But most of all carry on with the naughty step and reward charts as it will take time, its not going to change overnight. Persevere it will get better with time and patience.
