Scheduling around a day of naps

[Dreamalittledream]

I would just put the two of them down around 9am and wake them up at 10am. That way they get a power nap and should be able to make it until 12:30/1pm for their afternoon nap.

This is exactly what I do and it works great for me. My one year olds are usually transitioned away from morning naps around 14 months or so.
Our job can be really demanding, the sooner you can get them all on the same sleep schedule the better for you to be refreshed
