We keep getting head lice, We have narrowed it down to a friend that dd1 only sees every two months when she is here staying with her Mum for the weekend.
We de louse every Sunday and we are clear for six out of the eight weeks. Then her friend comes to stay or dd stays at hers and a week later.. there they are. It is dd1, dd2 and me 
I don't want to stop the friendship but it is driving me mad. Dd1 is 13 and her friend is 12 so too old for me to say " let me check you" and even if I did the follow up wouldn't happen.
I love the girl like she was my own and have spoken to her GP'S who have her for the other time but they say she is clear 
I just can't afford to spend any more on lyclear or whatever so am only on the conditioner and comb method.
My 2 yr old is suffering too and I worry about her going to nursery, advice please I really do not want to stop contact but I am going mad with scratching.
I am also worried that it is not her and would cause heartache for no reason .. so stuck.
