I have just been through what iw ould call a wee regreesion with my dd who has just turned 6.
She was wetting herself for 2 months, and I mean every wee.
Inthe end after testing twice for infections (came back clear), and at my wits end I started her on a chart.
She never had a chart the first time round, when potty training, yet somehow this smal thing, took the focus away from the wee.
What I mean is, a wee on the loo was now a positive on the chart. Each wee got a cat drwan on the chart (she adores cats), and each cat made some money.
I was really stuck before we did the chart. She has been having emotional issues for a long time, as her dad and I are divorced, and just recently had been very unsettled.
I would always be clam and tel her it was ok, that she had we'd, but that wasn't getting us anywhere iyswim. Nor could I berate her for it.
If it carries on, do try it. My dd got to the point where she just had no control, couldn't feel herslef going.
So with me prompting, and the chart, it really worked.
