Sorry, I thought I did mention it.
Yes, resistance can be up to an hour or even more. Thatès how he get's himself to 9pm. However, I realize now that that was only because I would put him down after 3hr of A time and he'd be UT'd. Now with 3.5hr A time before BT, he goes down much easier (only about 15mins of babbling/light crying).
I think I'll stick to a longer morning nap since that's what he's used to now. Also, because nap 2 is always harder, I feel like it'd last until 530pm.
What you said about a later BT makes sense for this phase. I guess 8pm would be the max since he still wakes up at night for feeds. If he has a good day, he only wakes up once around 5am and then up for the day at 640am.
Right now this is what I'm doing (since Saturday)
640-7am WU
1040am nap 1 (Saturday=2hrs/Sunday=1hr in bed and 1hr in arms)
340pm nap 2 (in arms for 30/45mins)
BT 740pm (asleep at around 8 )
