Friend seems to feel my dd has given her children nits. My dd had nits and it took ages for me to get rid of them (even cancelled a meeting with friend because of them) but when she visited week ago last Sat, dd definately didn't have them. Got a phonecall on Mon 7.45am from her saying kids had nits. Now her children go to nursery and have other friends so surely they could have picked them up from anywhere?
