Last year, a my DH's work colleague's daughter had a mild reaction to peanuts. Tests by a allergy specialist were negative. Her mum (Indian descent), on Tuesday, made a decision to give her fussy child, who was home from childcare, suffering from conjunctivitis, some peanut butter on bread. Wham big reaction, hives and swelling. What is scary is that she did not call 000 (Aus emergency service no), she waited for her husband to come home from work. My DH gave her a lecture about how serious PN allergy was and that she should have called for help.
Hopefully she will be able to have the child re-tested and gets the correct DX arm herself with the correct information needed to keep her child safe.
