The simplest answer is this:
Wednesday morning: both girls sprout fevers without any other symptoms [we were out]. We returned home and went into lockdown mode.
Thursday: Still feverish (103 without Tylenol/Pamol)
Thursday 6:30pm: Naomi goes to bed because she's exhausted from not taking a second nap.
Thursday 8:00pm: Naomi wakes up thinking it's time for her "nap" to be over. Oceana gets ready for bed [going to bed late because she did take a nap, and screwed her bedtime up].
Thursday 8:30pm: Oceana goes to bed. Naomi refuses to settle.
Thursday 10:30pm: Naomi finally settles back down and goes to sleep.
Thursday Midnight: Momma heads for bed, grudgingly, as Daddy is away for 2 weeks and Momma doesn't sleep well when he's gone.
Friday 1am: Oceana wakes crying; wets pants on the way to bathroom [presumably too many unchecked fluids and too sick to notice the urge to go till too late]. Change clothes, clean up mess, take child to my room. Settle in to sleep.
Friday 2am: Oceana wakes crying. Fever is back. Get sippy cup of water. Find thermometer that has wandered off [argh!], dose again with Tylenol. Settle in to sleep.
Friday 3am: Naomi wakes crying. Feed baby. Fever is back. Dose again with Tylenol. Naomi does not settle.
Friday 4am: Naomi still not settling. Momma gets out of bed, proceeds to pour herself and baby a cup of cold water. Momma pulls out the cookie bin and eats two cookies at 4am.
Friday 4:14am: Waiting for Naomi to resettle so Momma can resettle and get more than 59 minutes of sleep in a row.
Tomorrow's gonna hurt.
We're gonna be fine. When their Tylenol is working they are happy-chappy and fine. It's just when their fevers come back that they get really out of shape.
If these fevers don't break by mid-morning we'll be visiting the doctor since it's Friday and I'm not waiting until Saturday night [when the ER/ED is my only choice] to see that there's something more than an icky virus going on.
