Hi Stefanie
I guess I'll try cutting back to 1 hr 15 min for the next A time after a good nap to see if that makes a difference.
Yes, it sounds like 1h20 is a bit too long for him. Try the 1h15 A after a good nap.
About 2 weeks ago I though last that maybe his A time was too short and was trying to extend it already then. It did seem to help and then things unravelled again. Maybe I upped it too fast or made it to long... I was trying to go for the 1 hr 15 minute A.
It might have just been too soon for him, but I think he's ready to make the jump now.
Re: your wind down routine--it sounds good! And you know when you've hit his sleep window juuuust right because of how easy he goes down with the shh/pat. Just a suggestion about the swaddle, have you tried calming him down and getting him drowsy first, then swaddling him, and then start the shh/pat? He might not get so worked up then. But I don't want to mess with a good thing, so take that for what it's worth
When he's fighting the shh/pat, I would say that, yes, his sleep window was missed (could be UT or OT) or he's OS.
1) If he wakes up after 30 minutes because he's OT, what is the best thing to do?
The best thing to do when you know it's a short nap due to OT is to try and extend. Like you said, use the shh/pat. If he's settling but crying again, back and forth, keep doing it until he's asleep. If he's just not having any of it, try picking him up, calming him on your shoulder/in your arms with the shh/pat and transition him like that back into the crib. This isn't the same as PU/PD...just to allay any fears.
If you know that he really, really needs the sleep and you don't feel like you can get him back on track for the rest of the day if he doesn't get a good snooze in right then, then yes, I think doing some APOP (accidental parenting on purpose) is okay. Then for the next nap, just go right back to the usual way of doing things
For UT naps, you've got the right idea!! You can try to extend by using shh/pat. But, personally, I have very, very low success rate at extending an UT nap. You can try to extend for the rest of the S time--who knows...your LO might go back to sleep. Or, you can just leave him in his crib to hang out for a bit, if he's content to be there. Or, you can get him out and do low-key activity until the next E time. Regardless of whichever of these you decide to do, after his E, you'll HAVE to put him to bed sooner. So, keep in mind that his A time will be from when he wakes up early, through the E, and just after. If you need to feed him a bit earlier just so that he won't be awake too long, go ahead.
2) What do I do in the middle of the night when he seems wide awake after eating?
As odd as this might seem while you're doing it, you lay him back down and...leave him to see how he does. He might drift back off on his own. If he starts fussing/crying, then shh/pat him. Of course, it really all depends on WHY he's not going back to sleep after his feed; but considering the situation, I think it's because he needs more A time during the day and so his body is making up for it at night. Unfortunately when it's that kind of NW, shh/pat isn't going to send him back to sleep any faster (believe me, been there, done that!).
When he wakes up at night, it's a good idea to get into the habit of hanging back and not rush in at the first sound he makes. It's incredibly hard to do as a first time parent, especially when your LO is so young. I don't mean letting him cry it out, but sometimes LOs wake up, fuss, and then go back to sleep. By hanging back and listening, you can learn his cries better (hungry versus self-soothing fussing versus wet diaper, etc.), plus there's a smaller chance that you'll become a prop to just put him right back to sleep.
That seriously has been one of the most difficult things for DH and I to learn. You know how it is when you're dead asleep and suddenly at 3 am, you hear crying! It's very disorienting.
Just as a parting note: I think you're doing a FABULOUS job!!! You pretty much answer your own questions, lol.
