Sorry for my delayed reply, we've had a busier week than last week!
I'm back to thinking that the paci may not be an issue, because he did have a night in there with only the DF and one other NF. What I notice is that the nights he goes to bed OT (after too long of an A time), he has a really unsettled night (well, the last one you posted may have been unsettled because of the BM as well). On, the 29th, even though he missed a nap in daycare, he had a later CN and less than 2hr A til bed and slept a good night. Otherwise, on the other two days, his A time before bed was 5+ and almost 3hr, likely much over his capability (although I know the one day was because of a missed nap).
So, I think the best plan is to try to get 3 full naps, or 2 full and 2 CN if that's how it works from daycare... a 12-13hr day, depending on how the naps fall... no more than 2-2.5hr A time to bed after a full nap, closer to 1h45-2h after a CN. I know it's hard with not being able to control things at daycare, but try that for a week or so and see if the nights don't get a little better.
