AIBU if the parents know their kids have lice to give you a heads up before letting their little angels climb all over you/ or your kids?
dn 8 and 11 have lice a lot and I am sorry to say it makes me not want to hug them or for them to be all over dd 
I think bil could give us a heads up or at least tell the girls who are old enough to not be hugging people and playing rough when they have them
AIBU?
I really dont want to cause a family issue but those poor girls have them a lot (mil usually does treatment as Mum and Dad don't and she only sees them once a week)
how do I approach it? never had it here yet (dd a baby with short hair atm but dreading it already and dont want to stop her seeing her cousins)
