My daughter is 7 mo old. We believed she had a milk intolerance/allergy. We switched her to soy based powdered formula. She received one bottle before bed on the night of 5/14. On 5/15 she received 2 more bottles. We noted a rash on her legs moving up the trunk of her body. Small red raised pinpoints. I called the pediatrician. Before we made it to our appointment i found she was running a 102.2 fever. Made it to MD. Initially i thought food allergy. MD thought hand/foot/mouth disease. Then she decided not due to labs with wbc 5.8. Eosinophils were elevated indicating an allergic reaction. And mildly anemic which we think is totally unrelated. MD said not bacterial or viral. Suggested alternating ibuprofen and tylenol. Its now 420am on 5/16. I've given benedryl for the rash twice which was believed to be part of the allergy. Fever is at 101.5. And now we've started vomiting green bile. We just gave her pedialyte. She's resting in her crib in a diaper. Further thoughts or suggestions? Im a RN and out of ideas. I thought roseola Maybe... But the rash and fever are concurrent. I'll take any help I can get. Thanks so much!
