A creak. We freeze (well, those of us still awake).
Distinct squeak of door knob.
We immediately rise, so we are already at the bedroom door when a bleary eyed little girl in pajamas, slippers and blankie-shield informs us (as she does most nights):
"I can't fall asleep."
To which we reply, "little girl, you've been asleep for hours."
Whereupon we will scoot her straight to the bathroom (after surreptitiously patting her on the behind checking for dampness that would imply it's already too late), where she may or may not require you to hold her head less she fall straight off the toilet in slumber.
And back to the (hopefully) dry bed, unless you let her sleep in the blue chair, recklessly.
And then we thank God. :)
(Exceptions to this routine include the prophylactic 'take sleepy girl to bathroom while she's actually snoring,' the "Mommy, I just need to sleep in your bed for a FEW minutes," and of course the "no I didn't fall asleep yet! I was just being quiet.")
BLI AYIN HARA!
