One thing I know for sure, Mom's should ALWAYS listen to their instincts. Pre-diagnosis, Alexa was very sick-vomiting every day-sometimes 2 or 3 times a day. I KNEW something was wrong-it was just nagging and nagging at me. I kept talking to people about it, but everyone said "she's fine-stop worrying" That nagging feeling continued. I kept track of what she ate and when she got sick and realized she was vomiting 2-3 times a day! I took her to a Dr., he told me "it's constipation, cut back her milk". I left his office thinking "He's a QUACK-something is WRONG with my child!" It wasn't until after Alexa had an anaphylactic reaction to peanuts that we found out she had multiple allergies which she had been consuming daily and were causing her to vomit and have a constant chronic cough. I've learned so much since then. Allergy mom's need to share their stories, learn from each other, and listen to their instincts!
