  Last night I awoke with a chuckle as Ellie latched on to my breast with a hot, fevered mouth. Then I realized it probably meant she's coming down with Strep, too, and it wasn't so funny. One of my fondest memories from my fumbly first months of motherhood after Aidan's birth is of Aidan's first fever. I love it because it reminds me of the huge change I underwent as I discovered my mothering instinct. I only grappled with whether to move Aidan from his co-sleeper to the bed for about three weeks, at which time I had developed enough trust in myself and appreciation for sleep to make the move to an unabashed family bed. Aidan would nurse freely off and on through the night and I would drift from the stage 3 mama sleep to stage 1 or 2 long enough to help him position himself, or pop him off and shove him over. During one of these middle of the night nursings, I found myself rapidly coming out of sleep with the realization that something was wrong with my baby.
When awake, I quickly realized the feeling of his hot mouth on my breast as he drowsily latched was what woke me. He had a fever! I woke John and we proceeded to discover the parenting drill of underarm (we'd already learned the rectal lesson! ) temp-taking and thumbing through symptom lists in the baby books. I don't remember what was wrong, it probably resulted in us seeing Dr. Ho and Dr. Ho sending us home empty handed with promises that the affliction would harmlessly run its course. That happened a lot early on. That's why interviewing a pediatrician when pregnant is so important.
Then, you're still level-headed enough to find someone that trusts the body over medical interventions. You can explain your anti-antibiotics values and the Dr. understands you aren't one of those people who feels cheated if they leave without a prescription. If you wait until you have your newborn to find the doctor and explain all this, you'll be under the first time parenting psychosis that results in frightened and freaked out reactionary approaches to each sneeze and cough.
So, having explained all that, what to do about Ellie's possible onslaught of Strep? Babies typically have a lighter go of the bacteria, but I presume they still run the rare chance of rheumatic fever. A considerable part of me regrets giving Aidan the antibiotic last week. For now, I'm just watching and waiting. This fever could still be a sudden tooth rupture.
