because I reported that DD2 has threadworms.
From reading old post's here & reading patient.co.uk etc, it seems the worms lay their eggs at night time. The advice is to treat with OVEX, then wash bums first thing in the morning to remove any eggs that may have been laid. Then use seperate towels to dry each memeber of the family & then wash the towels.
Isn't it a bit over the top that DD1 has been told to only use this pencil ?
