Wow! Wonderful routine! So your gut feeling of an uncapped nap at 11.30 was spot on - Go Mama!!!
On the E routine. Looks fine. The morning milk feeds are a little unusual but some LOs just don't like to eat first thing when they wake in the morning and need a bit of awake time first. So long as he is feeding well, it's fine.
I am assuming there is another milk feed just before BT too.
WRT props and feeding to sleep, if you just rouse him a little before putting him down I'm sure it will be ok. I used to tell mine (if he ever nodded off before he was in bed) quite loudly "I'm putting you into bed now so you can sleep properly. Call if you need me" so he was truly aware that I was going. He usually opened his eyes a moment then went to sleep.
Really, everything looks really good. Hopefully this routine can continue for you so you feel the predictability of the day again. Well done you for listening to LO and finding where his best sleep would come
