Big (((HUGS)))! My LO just started crawling etc., and I am in the exact same boat, complete with the EWs!!! I could have written your post. Not that our EASY was ever perfect to begin with (far from it!), it seems that even now the few things that did go well aren't anymore!
It's so exhausting, isn't it?
Naps have never been great for us, and we've always had at least one NWing, but DS used to at least go down to sleep easily and he would sleep until 6:30 or 7. Now since he has been crawling and pulling himself up, putting him down is a total disaster, and he's up before 6 every morning! At first it was 5, but now we've got it at 5:45.
I swear we are the same - teething here but Tylenol and Orajel are lost causing. Had a bit of a cold, passed quickly so I know that's not it either. I really feel it's the new mobility. I try to give DS loooottttt of practice time crawling and pulling himself up. As much as I don't want him to get OT, it's kind of unavoidable and I actually feel like he just needs to get it out of his system, so I let him go nuts.
Something also I didn't think about is when they become mobile they get OT much easier, so A times might have to be reduced significantly until things settle again. I know, easier said that done! I've played with all lengths of A times too, but I'm actually finding 3hrs to be the best so far, I can get a 1hr or 1hr 15min nap out of him then.
Have you tried walk in/walk out (wiwo)? At this age ssh/pat is too stimulating and actually becomes ineffective. I've recently started wiwo and I have to say I think it's helping. I use it to get him into bed at night, and also to extend naps. It's for older babies and is particularly good for separation anxiety. Here's the link, maybe you'll find it useful.
