Thank you again for your replies.
Today, again, a weird day.
I put him to bed for the night at 6:05 pm because of the last nap ending at a weird time and not having enough time for a CN. He slept without a peep until 6:22am! He has done this before when his A time is over 2.5 hours before bed (rarely is). I'm wondering if the CN takes from his night sleep now. With the CN he wakes around 5:30-5:45am a lot and will sometimes put himself back to sleep until 6:30, mostly not.
So, with him having almost 12.5 hours of sleep last night, so far our day has gone like this:
Wake up at 6:22am
Awake until 8:35 (alseep at this time, out in 2 mins with zero fuss)
Woke up from this nap with no interruption in between 50 minutes later at 9:25. He talked in his crib for a few mins happily and we went in and got him up.
Next nap was at 11:39 (2hrs 15 mins awake). It took him 4 mins to settle in his crib with light fussing and one roll before he was out.
BUT, he only slept for 30 mins! We left him in the crib and watched him talk to himself and play with his shirt and hands for 15 mins. No fuss at all. He rolled onto his back and then back to his belly and put his thumb in once or twice like he was going to go back to sleep, but just rolled onto his back instead and was talking. Went in and got him up. It's been an hour since he woke up and he's as happy as can be.
If his night sleep is so consolidated and long, could this be one reason for short naps? Also, I am beginning to wonder if I should continue to try and extend the nap by leaving him in the crib to fuss or talk.
It's so frustrating when I try to make sure he's either not OT or UT. I try and try and can't seem to get it right. I read that it can take past 6 months for babies nap rhythms to mature. What is your take on this?
At this point, I'm going to follow his signs until I put him down again. Today he never got cranky, he just yawned a few times, but zero fuss. Maybe we should wait for him to fuss?
Thanks again for your help.
We have let him cry at times for a couple of minutes, but when it turns into a hard cry, we will go in. He mostly grunts off and on, and fusses so we've found that leaving him alone to try and settle is what works for him. Believe me, we tried every other method before doing that.
