Oh, Laney Bug!

A few weeks ago I decided to introduce Laney to puffs and whole wheat cereal. Jareth loved his puffs and I was excited to share them with Laney too. So oof to the store I went to buy some of these yummy treats. I picked out sweet potato and vanilla as kind of a treat for her. As soon as we got home I put her in her high chair and gave her a little cereal and applesauce and a sample of each kind of puff. And boy, did she love them!
About two hours later I went to change her diaper and, "Oh, Laney Bug!" Her tummy and back were both covered in hives. I'm not just talking about those little red bumps kids sometimes get when something irritates their skin. I'm talking huge golf ball sized, swollen circles. I looked at her face and she was happy as a lark but her skin was bright red and just looked terrible. I'm proud to say I didn't freak out and rush her to the ER or doctor's office. I decided that since she didn't seem to be bothered by this reaction and didn't have other signs of ailment, I would just watch her the rest of the day and see if they would go away on their own. After a day or so, without any wheat, they had lightened up a lot so I decided to test it out again. I think I gave her three puffs and within an hour her skin had flared back up and even her head had broken out a little. I called the doctor and they said not to give her anything else with wheat but that they couldn't see her for another week.
A few days later Jareth was eating some scrambled eggs and Laney got a hold of a small piece. Her face immediately broke out in streak like red marks. Great... No wheat and no eggs for Laney Bug. When we finally got to see the doctor he assured me that she wasn't under any immediate threat and suggested we do an allergy test. I opted out, worried about how invasive it would be. So we decided to wait until she is one and if she still shows allergic symptoms we will do one then. He also said if it seems like the hives are reappearing without wheat or egg exposure we could go ahead with the testing.
Her skin is still flaring up almost everyday but I'm not sure if it's because she has gotten into something with wheat traces (Jareth drops crumbs constantly) or if it's due to something else. I don't know what to do. Her skin looks awful. However, she doesn't seem to mind it and I do have some peace in that. Oh, I hope she grows out of this!
