When my child was a baby I played tons of games, because they napped so much.

My wife and I would each take an 8 hour shift alone while the other person napped, and an 8 hour shift together. While I was alone and my child was napping for a couple hours at a time, I could get in a few games.

This, of course, relies on you living somewhere that gives reason amounts of parental leave to both parents.
Once my child got older, and started sleeping through the night, and we had to go back to work, then the shift system didn’t work anymore, and my gaming took a precipitous decline
