I can bring my kids in but I don't think I could tell you how they work. I've been in this industry for almost 20 years, but I don't have side projects, because, well, see above.
By which I mean I'm potty training my 3 year old.
Maybe your view would change if you were actively looking for work? Spend a week on some fun project while taking a break from resume writing.
Meanwhile, you get to spend more time with your kids.
