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.
