So I realize this may be nitpicking, but I often have no idea when exactly my LO woke up. A lot of the time he wakes up and just hangs out quietly in his crib until I get him. So.... do you time the first nap of the day according to when you *think* LO woke up, or when you got LO up for the day? Sometimes I'll leave LO in there for 15-30 minutes if he seems perfectly content. But like I said, I really have no idea when he really woke up!
(Not sure it matters, but he's almost 6 months, and his awake time is about 2 hrs).
