<s>[INST] My almost 9 month old has a rash/hives around the edges of her diaper, armpits, belly and backs of her legs. We just started introducing solid foods. We introduced oatmeal yesterday. She had a virus a week ago. No fever, just vomiting for about 8 hours. She s had a bit of loose stool this week. is this a food allergy or a continuation of whatever she had last week? [/INST] HI ...this is not suggestive of food allergy. This is classically fitting into eczema as it is involving the flexural surfaces of the body. The trick of the management is keeping the skin moist and never allowing it to be Chat Doctor.  For this oil massage and lotions like Hiatus will help. But usually kids grow out of it...that is as the age progresses, they become better starting from 6 months of age, and they gradually get better. Regards -  </s>
