Ack....we have a very similar pattern going on here with EW, then NWs, 2 really good naps, and then everything goes to pot and crumbles. Yesterday we had a PM nap refusal so DS was up 5 hours
Magically, we tried the neighbor's swing and he fell asleep for 35 min - this has never ever happened before. Alas, we had many NWs as a result though....
If I figure anything out, I will keep you in the loop. In the meantime, I'm trying to roll with it as best I can without going crazy!
Big hugs!
