Hi Shiv!!
I hope you and your family enjoyed the birthday weekend

The other night he was a bit easier to resettle but last night we had the same issue with him staying awake for an hour or so between 10-11. Of course I attribute it to not enough A before his CN (we were out), growth spurt, and maybe too long of A after CN.
I do think it's the GS influencing unsettling at bedtime because I noticed that he wanted to sleep. He kept wanting me to lay him down but he would toss and turn trying to get to sleep. However, he would work himself up so much. So far the morning nap is good and consistent (no resettling), afternoon nap I still have to resettle. Also last night he was waking up every 2-3 hours in the middle of the night wanting to eat. usually despite the ENW he goes the rest of the night without waking.
I agree consistency is key; however, I am still trying to figure out the right A after the CN. Also I'm thinking of gradually making his WU 7:30 am.
DH has tried to do bedtime but LO is more difficult with him.
