I'd agree that steering clear might be wise.
There is no history of food allergies, or even asthma or eczema in my family, yet...... I ate a fair bit of peanut butter during my pregnancy, and my son now has a peanut allergy (as well as other allergies). I definately cant say whether its related or not, as there are other factors present (such as me not BF, and starting him on solids too early) which equally may have attributed to his allergies.
