Skin reaction - Tomato allergy?

tbmadeamistake

Just looking to see if I'm crazy.  When LO was starting on purees (4-5 months) both sweet potatoes and tomatoes gave her tiny little hives sort of sporadically around her body.  She's now 2 weeks shy of 1 year and we've been giving her tomato sauce for a few weeks.  Within the last week she's been getting excema like patches, mainly on her back with a few on her arms/legs.  No sign of anything on the face, which was our first clue when she was younger.  Sensitive skin like mom or a tomato allergy?
