I don't get the impression that he's teething (no unusual grumpiness, naps have been good, etc), but he's just started to sit up independently for short periods of time. Just the other day, in fact. I'm still thinking that there needs to be some tweaking with A times, though.
Also, it's so tough to know when to put Jesse down for his first nap now. For instance, he was up at 5:45 this morning, fell in and out of sleep from 6:10-6:40 and then he was up so I fed him at that time. He was rubbing and scratching his eyes so badly that I knew that I couldn't have gone the 3 hours till nap time (which would've been around 9:40) so I put him down at 9:20. My theory was even if he had slept soundly for that half hour, tack that on to a 5:40 wake up and you're still only at 6:10, which makes 9:20 a good long A time. Does that make sense? I'm grasping here. I'm really worried that he's gonna be a tough one with development. Gavin, my oldest, could and still does sleep through everything. I thought he was a touchy sleeper, but nothing compared to this LO...
I should also note, that my hubby said he was pretty much awake from 9:20-11:00. He went in, gave him the df and he CONKED out. Could it be possible that some of these wakings are hunger related and he's just being disturbed from sleep by a hungry tummy? He's back to taking the same bottles as he was before starting solids and he's eating 6 tablespoons of solids a day. Can't babies just tell you what's up?!?!? ARG!
