That EASY you posted is pretty much bang on hun
My LO started this transition around 10 mths too and liked a long AM nap (if I capped that I got 2 short ones.) Pus I liked to be able to fall backon the PM if the AM was a bust
We did this (which is very similar to you)
WU 6.30 ish
A 4.5 hrs
Nap 11 for as long as he likes
If nap ended after 1 and he was coping ok, EBT of 6pm.
If ended before 1, or Z seemed tired we did
CN 4hrs.15 mins later in the car (APOP) for 30 mins then BT 2hrs A later. (usually 7/7.30ish)
What I found is at first we had lots of CN days, eventually they got less and less, and then Z refused them.
With the main nap I also worked on gently pushing it closer to 11/11.30 over time, and if the nap was less than 1.5hrs I tried to resettle (APOP - any way I could) to encourage the long nap.
Does that help at all
