E's finally on the mend. She's not yet back at school, but we're giving certain meds less often, and I can actually envision sitting down with KM today instead of crawling under the covers when E takes her nap.
By the way, we ended up starting steroids over the weekend. As much as I hesitated doing so, it was the right decision. Within 12 hours we noticed a difference. E was still coughing, but the cough had changed, sounding less labored, more productive.
E still has a ways to go before she can return to school, but we're headed in the right direction, thank God.
