Wake windows/naps

Just curious. What are your baby's wake windows and naps like? My baby sleeps for about 12 hours overnight(with multiple wake ups). Is up for about 2-3 hours and then naps for about 1.5-2 hours. Then has a 4-5 hour wake window and then it's bedtime. He's been on a one nap schedule for a couple weeks now and if he takes 2 naps then he is awake until midnight or later which is a struggle now that I am working. I would like to go back to a 2 nap schedule mainly for some more time to myself in the evening but this is working for the most part.
