hi there, just after some advice really. My dd is 7 and has threadworm again, this is the fourth infection over the past couple of yrs. We are treating her with ovex, washing etc etc. The problem seems to occurring because she puts her fingers into her bottom. I only found this out when I noticed small smears of poo on the bathroom wall. Gross I know but true none the less!! I have asked her why she is doing this and she tells me it is because her bottom itches. I have asked her to promise me not to do this again but I had the same conversation with her a few months ago. I can't watch her all of the time and have stressed the importance of hand washing etc but she doesn't seem to really take much notice. Help is it just my daughter doing this?!
