He does it all during the day, can go for long periods (a few hours)without doing it but can wash his hands 4 or 5 times in 10 minutes and he is making his hands sore. He had a bad bout of norovirus earlier this year and is terrified of picking up germs on his hands now. I try to ignore it hoping it is just a phase but it is driving me mad, I feel sad and frustrated for him, I hate to see him uptight about it. Any advice would be much appreciated
