My brother has some pretty frightening allergies to some nuts and seeds (peanuts, sesame, brazil nuts, etc) and has had a couple of very life threatening situations after contact with macadamias.

I just read that : 'If you or members of your close family suffer from peanut allergy or allergic disease such as atopic eczema, asthma, or hayfever, it is recommended that you should avoid eating peanuts or food containing peanut products during pregnancy and whilst breastfeeding.'

This is the first I've read of this and it has me a little upset as I thought it was only about avoiding nuts when breastfeeding and not introducing the baby to nuts until they're 3 years old. I've been having peanut butter probably about 6-7 times a month and thought that my snacking on a handful of unsalted cashews or some trail mix was a nutritionally positive thing.

I'm a bit bummed about this now but I can't cry over spilt milk...what have you all encountered in this department??
