a late night / early morning moment in the life of a toddler's mom

So Declan woke up wanting to play sometime around 1:30am. I suspected he was awoken by a pooping session. My suspicion was confirmed by Daniel around 1:50am. Commence attempt to putting the baby to sleep again around 2am as I drifted between consciousness and conferring with a group of phantom parents about Declan's odd behaviors. Failure by 2:20am resulted in my leaving the bedroom upon Daniel's request (Declan usually calms down enough to sleep when I'm not around. Sigh). It is now 4:22am.

Should I sleep now or just pull up the document I need to translate and get it over with? How am I going to feel in the morning?

And where did the last two hours go? Aside from my fighting the temptation to boil up and consume some dumplings?
