I was at a bbq with my one year old today and a few bites in I noticed she’d suddenly got what looked like hives all round her mouth and on her cheek. Literally all she’d had was 3 bites of hotdog, one of burger and one of chicken. She’s had chicken before and while she hasn’t had a burger she’s had beef mince etc so it looks like the most likely candidate is the hot dog :/ google suggests some people can be allergic to the nitrate in hot dogs, has anyone heard of this? And what do I do now? The rash has gone now but I’m thinking I should probably still take her to the doctor? Will they even be able to test for this or will they think I’m nuts?
