Am posting again as not much response to my first post. I have a 2.8 year old ds. We've been potty training since the end of June. We had wee cracked for at least six weeks but....in the last fortnight he has been gradually regressing to the point where yesterday he had four accidents. I don't think he is particularly upset about anything so don't feel this is psychological. What do I do? I am prepared to put him back into nappies but dh feels this really would be a last resort and is not keen. Help please - even his nursery seem a bit unsure about what to do.
