Thanks, mom of two...yes, that makes sense to me that he can handle more A when he is well rested!
Alexa, as far as milestones, he started pulling up to stand about 3 weeks ago. He does like to practice this...all the time during A. And I think you're right about sometimes giving more A so he doesn't have a crib party before the nap! I try to make sure he's drowsy before I put him down, sometimes he goes to sleep within a few minutes, and other times, he pops up laughing as soon as I put him down! Maybe when he does this I should let him out for another 10 min or so, then do a short wind down again.
Yesterday was quite messy, as we were out and about with the family. He was so tired that he fell asleep while taking his bottle at 6:50. He slept through until 6:25 this morning (I think). I heard him chatting at 6:25, then it was very quiet until 6:45...so I'm not sure if he was up that whole time or not. I didn't want to peep in because when I do that, if he's awake and sees me, he wants out right away! So, I counted A from 6:25...just in case! He was pretty still and quiet for wind down, and I just put him down a couple of minutes ago. He's not asleep yet, but just moving around pretty quietly. We will see!
