My partner has children who stay with us every other week for 7 days, they are amazing kids but they have constant headlice. When they come to us my children catch them and I spend a fortune on lice treatment not only for my kids but for his too. As soon as they go back to their mum the treatment stops. I asked him to have a word with her which he did but nothing has changed. Today I told them if it isnt sorted I wont have them here. He went mad and said I was out of order. It's my house too though and I'm fed up with it. Am I being unreasonable saying I wont have them here until the lice are gone? This has been going on for months and I've had enough
