Hello Hun, (hugs) and welcome. Can you please answer this...
Are they independent sleepers?
It's really quite relevant to how you move forward. What we're asking is if you are able to put the girls down awake and if they can get themselves off to sleep ie: self settling.
About the schedule you suggest, only 2:30 A time for second turn and expect them to sleep 2 hours. Which is a dream for my girls. After 4h A time, they sleep only 70-75mins
Those 70/75 min naps may be over tired naps due to the A time being too long. Also Becky is suggesting a 30 min nap instead of an hour which makes a big difference to the length of A time before the 2nd nap. It is basically one of the 'typical' routine's for LO's of the girls age, but of course it does vary and we/you need to figure out what is best for your girls
The short am/long pm routine works for many LO's because the short morning nap is less likely to result in 2nd nap refusal, and make it possible to keep the day shot enough, which I would suggest keeping at 13 hour maximum.
At 1 year old LO's rarely still need NF's so I am sure you're right when you say they don't need a feed 3 hours after the last one. My thinking is that the NW and EW are routine related. IIWM I would drop all feeds at night now, because they really do become a 'prop' which is hard to break

Bye for now
