just got the anaphylaxis campaign newsletter and it reports a study where applying peanut protein extract to broken skin on mice interfered with the process whereby tolerance is induced when peanut is eaten. Quite a long way from that to saying that creams with oil in may cause allergy in some children but another reason to check creams carefully.
Study reference is "Epicutaneous exposure to peanut protein prevents oral tolerance and enhances allergic sensitiation. J Strid, J Hourihane et al Clin Exp Allergy 2005; 35:757-766
Interesting article about different responses of parents to a child's allergy, made me think about how much I do compared to my husband.
