I'd be interested to hear when people introduced nuts in cooking to their children with other allergies but no KNOWN allergy to nuts.
DD is allergic to egg and has an intolerance to milk protein and soya. As is the way these days, she was not tested for things other than those we presented a problem with already. Obviously we will avoid peanuts until she's older and her consultant said we'd discuss it again in a couple of years which I guess might mean he'll test her if she hasn't had accidental exposure in the meantime which will tell us either way 
I was wondering where things stand re giving her things like ground almonds in cooking - it would be a nice source of protein, calcium and calories... but I'm not sure if it would be playing with fire and best left alone? I guess I'm going to have to expose her to these things sometime though? I can't expect to wait for her to be tested for every known allergen right? Or are nuts a different case entirely?
I guess it's about how we all manage risks and it's very individual and varies according to the circumstances but I'd be interested to hear about others' decision making processes.
