Did your LO fight sleep before accomplishing a new milestone?

DS has been *thisclose* to walking for awhile and the past couple of days have been brutal, sleep-wise and just in general. He's 12.5' months and has taken a few steps but generally just cruises like a boss.

I'm grasping at straws here. I don't know why he won't sleep but I haven't slept for days either.

He's just been rolling and flipping and crawling all over the bed and seems so happy go lucky despite it being 2am,then 3am, then 4am...

Someone please tell me this was how their LO was right before they started walking.
