I have been battling head lice on my 5 year old since she started school a couple weeks ago! I tried the generic form of Rid/Nix 3 times, and done the name brand Nix 1x now. I have vacuumed to the point of my vacuum complaining, changed sheets at least every other day (my washer and dryer are whining too about all the extra work! But that is partly because I am also trying to get rid of pull-ups at night for my 4 and 5 year olds) and done everything I can think of. Right now my daughters are upstairs in the playroom smelling like vinegar b/c I just saturated their heads in it. Supposedly it makes the eggs slide out easier. I am about to go steam clean their mattresses and floor. I put away in a plastic bag all hard dolls with hair, every stuffed animal has been washed in hot and dried. What else can I do? Will saturating their heads in baby oil help (I was thinking it might suffocate these dumb critters, the bugs and eggs, not the kids!) ANY advice? PLEASE??
