I've named my time constraint

And her name is Vera. She's almost 4 months old, cute, and weighs around 7.5 kilos. She's a handful and requires both my and my wife's attention.

Because of Vera, I don't have as much time during my free time. I have to be a bit choosy on post-work events, and scheduled every Saturday to spend time with her.

I've learned to focus on the things that are important, and to disregard ruthlessly those things that are not.

It's not easy saying no to things I enjoyed doing before Vera. But when I think about how much I enjoy being with Vera, I'm happy saying no.
