So my almost 6 month old was born "awake" and super alert to the world.... And she's stayed like that. She's so happy throughout the day, but only takes two or three 25 minute naps per day. On top of that our nights have been really rough the last 2 months (a 5 hour stretch followed by waking every 1-2 hours.) Everyone comments on how happy she is, she's perfectly chunky, and really alert. She's also been hitting milestones early, so the doctor isn't a bit  concerned. I'm the one losing my mind from overtiredness.
