Audra was also more fussy than normal this past week - crying whenever I'd put her down and/or go in the other room, screaming and crying hard with Ryan while I was out with Josie one afternoon and only stopping to inspect a knot in the wood floor of the porch (and for Josie, once we returned). I suspect it's a combination of being tired (she had only napped for an hour total before I had left with Josie) and another development leap. My trusty "Wonder Weeks" book says this is to be expected around this age, as babies start to understand distances more and it becomes more alarming to them to see how little they are in this big world, and that their caretakers are further away than they'd prefer. But then Audra took a 3.5-hour nap one afternoon (after a half-hour nap in the morning too) and was simply delightful for the rest of the day, so maybe it is just more tiredness than anything.
But even when she's fussier at home, she's able to calm down and bring out some smiles and giggles so long as Josie is around :) Josie usually just needs to look at Audra to make her laugh, but Audra makes Ryan and me work for it a bit more. Our go-to methods of getting her to laugh are for Ryan to rub her belly with his head, or for me to blow raspberries on her belly or kiss/nom on her ears or neck.
We continued with no swaddle this week, and while Audra usually wakes every half hour before I go to bed now, there were a few nights where she went an hour or an hour and a half before waking the first time. She also has started stretching out her night-time wakeups after I go to bed again, going from every 1-2 hours all night, to a few nights of every 2.5-4 hours. The 4-hour stretch of sleep has only happened once (in recent memory, at least), and it was amazing, except for the fact that I must have been laying funny - not that big of a deal when I'm just going to be awake in an hour anyway, but it's a bigger problem when it's that long of a stretch, and now I still can't move my neck. Ah well, it was still worth it ;)
