After having a low grade fever off-and-on for a few days, Ivy woke up looking like this (several weeks ago): Note the swelling in the face as well!
The poor thing had broken out in hives! I promptly took her to the pediatrician who said the fever was caused by a double ear infection and that the hives were likely an allergic reaction to the infection. (I didn't even know that was possible.) I felt so bad that I didn't take her in sooner, but I used to take Millie in for every fever and it was usually nothing! Although she had a fever Ivy was still a pretty pleasant kid, so I thought she was OK. Even with the hives itching terribly, she never complained. She is such a good baby. Luckily a little Benadryl and a round of antibiotics cleared everything up. Now she is doing great.
