I did it with two kids (both were in school at that point, which helps). It -is- a lot of work. I spent maybe an hour a day during most days of the week, and then for some things I'd try to get a few more hours early or late in the day on the weekend. And for the most part I only did one class per semester. I did two for one semester because they were both expected to be fairly easy, and that worked out, but I definitely wouldn't do that with GA or any of the ML stuff.

It's doable, that's all I'm saying. But you will definitely need to be committed to see it through to the end, and you will be happy to have your life back when you're done.

As a childless OMSCS graduate, I also can’t imagine doing it while having kids, because it took basically all of my free time. That said, I met quite a few people in the program who were in situations similar to yours. I have no idea how they managed it, but they somehow did.

There's a web site where different people share what they think of each course, and how many hours they devote per week: https://www.omscentral.com/

That might help you decide whether it's doable.

My first (and only) course was somewhere in the middle in terms of effort, and the courses I was most interested would have required another 50% on top, which wasn't going to work for me, between work, parenting, other learning etc.

One course per semester might be doable? Not sure how frequently the assignments are due because you could probably carve out some time over the weekends.
