She's 5.5 and for the last 2 yrs has been a very competent rear-end wiper, hardly ever ANY skids (sorry TMI but YKWIM)
For the last couple of weeks or so she has regularly left evidence that she hasn't wiped properly
Why could this be? She knows how to do it properly. There's quite a bit there sometimes! I've no experience of poo problems so any advice much appreciated
