DD is 5. We've only really noticed this in the last few weeks but it is escalating. She is going to wash her hands more often than is normal, rather than standing there for ages washing. We've spoken to her about it and said she only need to do it after going to toilet and before eating. Now she is making things up, like just now said she was going upstairs to find a toy, but in fact it was to go up to the bathroom to wash her hands. Or she says she needs the toilet when we are out, and she doesn't she just wants to get to a sink. She says she is worried about germs and seems unable to control it - I'm worried about it getting worse. She has no SEN.
Any advice please?
