My dd is 9 months old and sometimes after eating develops a red chin with small red spots which then gradually disappears. It seems to only happen after she's eaten mature cheddar or goats cheese, she is fine with porridge/yoghurt and has never shown any reaction when EBF and is generally a happy smiley baby. I'm not sure if I need to take her to the gp or whether to just cut out cheese for a bit? Anyone have any advice please
