I took a c rail to the tail bone about 6 years ago in Steamboat and my legs went completely numb. So had ass pads and they work well then someone ganked them, then a company promised to hook me up with some and that never happened, then I just sucked it up and dealt with it. But if you do get compression shorts make sure they have the tailbone piece that's the one you really want. Most don't actually have it and concentrate on the hips/quads.
Oh and Slyder at your level of riding with 2 kids and age you need to have some sort of protection. You didn't start riding when you were young and grew up around knowing the body/spatial relations.
