If you have a doctor that treats your allergies, it might be a good idea to ask him or her about the kitten. I take allergy shots, and they include an antigen for cat dander. It seems to have really helped.

I also rinse my cats every couple of weeks with warm water to cut down on the dander (it's the residue of the cats' saliva from when they clean themselves). I don't use soap - the warm water is enough to do the job. But since your kitty is so young you should probably check with your vet first to make sure it's OK (she might be too young to tolerate a bath).
Another good idea is to have someone else brush her for you, so that you're not breathing in all that dander every time you brush her.
Also, try to remember to wash your hands after you've petted her, and don't touch your face while you're petting her, or put her fur in your face (I know it's tempting).
An air filter for your house (especially the bedroom) might help, too.
