Our 19 month old is waking at all times of night and NOT going back to sleep... for hours. It has been frustrating-- and with 3 kids, we need that night time 2 hours so badly to get things done (lunches, dishes, clean ourselves, finish a sentence...) that it feels like such a violation when one of our kids doesn't go to sleep/stay asleep.
We tried letting him watch Sesame Street in the Pack & Play-- lay down with his sisters in their bed, cry for a few minutes in his crib... no dice. He was up... LOUD and up. We finaly left him in the P&P with some Sesame Street (Sleepytime Songs) and tried to at least finish up all the kitchen/lunch stuff. Finally-- we needed to just try to get him back to the crib... at 10pm...
He was all sad and my husband was going rock him down and I was annoyed... and he goes, "He's just a little person, he doesnt know-- he doesnt want to be annoying us"
And then i felt awful and said i'd put him down myself and I'm glad I did-- it was cozy. At one point I was singing along to Renee & Jeremy's It's a Big Big World song, and the end of the chorus is "do doo doo doo, doo do do doo"... and I'd sing the first "doo doo do doo" and whisper "now you"... and he'd quietly smile and say "doo doo doo". It was a moment. I realized how little he is right now... how much he needs me, how sweet and wonderful he is at this age--- how I will miss having the strength to hold his weight for 30 minutes and bounce on an exercise ball.
I was like AHA!... of course they have to annoy you or you'd be a mess all the time wanting them to stay little-- but the waking and such keeps you wanting them to grow
It's JUST enough to make you excited for a new stage.
