The Sleep Issues (How am I Not Bald?)

I have to admit, I hate bedtime.  I dread nightfall with every fiber of my being.  (This is probably payback for when I had a snarky reply to my ex’s “Kids mean you never sleep again!” comment/argument against having children.  Fucking karma, you’re a bitch.)  Bedtime is obviously inevitable and sadly the extreme issues come in waves.  Right now, we’re smack dab in the middle of the WORST WAVE EVER. 
8pm rolls around and Rizzle, the youngest, is fairly ready for bed.  After a couple of stories and fluffy mama snuggles, she puts herself to sleep (typically with no protest) with her dolly and musical seahorse.  Nice, right?  Well, it’s all downhill from here.
Px, the terrible two-er, is visibly tired.  He woke up from his nap 6 hours ago.  We’ve done sensory activities throughout the day.  He’s in his squeezy/pressure vest and has been for half an hour.  But he’s two, and stubborn, and probably on the spectrum, so he stims.  He runs back and forth a thousand times, or digs a car out from under the couch (the ONE FUCKING TOY WE MISS), or plays throw the lovey across the room.  Every time he begins to relax, his eyes all heavy and sleep seconds away, he launches himself off the couch and into a stim.  Daddy and I are frazzled (hah.  understatement of the year.) by 10pm, sometimes 10:30pm, when he finally lets sleep come.
If we’re lucky(!), Rizzle stays asleep until 11pm.  But then, it’s 1-2hours (maybe more!) of pure insanity.  She wants bottles, and Tylenol, and her coveted fluffy mommy pillow.  No, Daddy will not do even momentarily so mommy can take 30 seconds to pee.  Don’t try laying me down without proper cuddling or I will SCREAM and SCREECH for-ev-er.  And definitely wake up my brother.
By this 1am time, my sciatica is flaring up.  My entire left leg is in throbbing pain, I feel hungry, and wind up awake for another hour or so.  But we best not breathe the wrong way or Rizzle will wake aaaaaagain.  For who the hell knows how long.  And occasionally wake Px, who will then be up for an hour.
What time is it now?  Oh hell, it’s probably best not knowing considering they will be up by 6am. So it’s best to just roll over, curl up, and dream of sleeping for longer than a minute at a time.
I think I may be permanently a sleep-deprived zombie now; cross in front of me and I will eat your braaaainz!  Mine is long gone so I need whatever I can get, with a side of coffee.  May no one ever make the “Oh she’s still not sleeping through the night?  She should be sleeping through the night BY NOW” comment to me ever again, I cannot be held responsible for my reaction.  I am a zombie now, after all.
