Hi Scouts mommy,
There is more about latex allergies in post #2 here.
There are different types of latex “allergies” that can be aggravated by frequent contact with the allergen (which usually aren’t the latex proteins themselves) but there is no evidence in any of the literature that I’ve seen (and I’ve read a lot of it) that sleeping on a latex mattress can increase your chances of developing a latex allergy.
