help-suggestions please..

My daughter is very allergic to cats and plays all the time with a friend who has a cat, both at our house and hers. She takes allergy medication and uses her asthma inhaler before she goes to her friend's house, and that's always made her fine; she even managed a sleepover over there. We tell her not to touch the cat, or if she does, to immediately wash her hands, obviously. We don't take special precautions when the friend comes over here (she's playing with the friend at school, anyway, and that's never been a problem).

before they come give her some
allergy medicine, claritin or something.
try to keep her away for the cat AS MUCH
as possible. ask her friend if she has like
a carrier cage or something the cat can be
in like some during the day so its not
running all over the place and spreading
its hair and stuff. and yeah try to keep
outdoors. maybe set up a sprinkler & get
some water balloons so they can play in
the water. stuff like that.

depending on how bad her allergy is if you are worried about a potentially severe reaction then just explain to the other parent that you need help can they wash an outfit and bring it over so that the friend can change into a "clean" no hair no dander outfit while she is visiting you. As a parent and someone with allergies I would totally understand if another parent asked this of me. We all want to keep our kids healthy and it sounds like this is a good friend they should understand.

Don`t know, but you should take care.

Well, first I would give my daughter her dosage of allergy medication. Let them play outside for awhile, and then you might, have them play dress up. This would cover the other child's clothing while in the house, and you the opportunity of washing the clothing they play in after she leaves, disposing of what ever bits of dander that transfers off onto the play clothes.

Just watch your daughter carefully, to see if she is shows any form of reaction.

You are going to be faced with this issue for many years to come, and hopefully, she will out grow her allergies. You will have no control over her being around other children with Cat's when she starts to school.
