I think DD1 (4 in December) has a nut allergy - peanuts specifically. She is fine with pistachios, almonds, cashews etc in fact everything except for peanut butter (groundnut oil no problem, not sure if that is significant). Neither DH or I or anyone in immediate family have allergies although my cousin has a nut allergy.
She hadn't really had peanuts/peanut butter much as it's not something we'd had in the house a lot. I remember giving her a PB sandwich when she was about 18m and she spat it out but I thought she just didn't like it. Recently she had some and immediately said it gave her an itchy tongue and spat it out again. A week or so later DD2 (12m) was having a PB sandwich (which she loves) and DD1 complained of an itchy tongue, so I guess some of the PB must have been on the chopping board.
I obviously need to see the GP about this and will make an appt today, but just wanted to ask for any advice/experience about what I should ask or be aware of - would appreciate anything from those of you who have already been there.
