He said that there are really rare immune-deficiencies out there that would make someone prone to staph infections, but that he doesn't feel like he wants to get into testing for those (pretty invasive) because people who have them have repeat respiratory issues, pneumonia, etc., and Kaitlyn's healthy as can be. Not to mention, he said that now we have an explanation for the staph that fits.
Dr. Johnson's biggest concern is Kaitlyn's weight-loss. He said if she's not vomiting and doesn't have diarrhea then he really doesn't know why she'd fall off her growth curve. Some possibilities he threw out there were a fast metabolism, her getting ready for a growth spurt and needing more calories than maybe she was getting. Or, food allergies.
So, that's that. We'll wait for the results of the blood tests. It felt good to have the immunologist confirm the dermatologist's findings, and I'm so happy that we did some more testing. I'm experimenting with some Burt's Bees products and so far am happy with them. I guess I still feel worried about the weight loss, but she eats so well, is developing fine, has eight teeth, and never stops crawling around and playing, so I'm resting in the fact that for now, she's okay, and we'll keep our eye on it.
Thank you so much for all your kind words, prayers, and thoughts. We are blessed!!! (Oh and I just thought I'd share some pics of my sweet baby girl.)
