It's amazing how much going to work feels like play time to me now that I've had children! You can generally take a break, go to the bathroom, etc whenever you feel like it, but depending on the age of the child(ren) at home, such activities often seem like luxuries to squeeze in whenever you finally have a moment to do so. I've generally felt like the most difficult challenges at work are easier than some of the problems when caring for kids, but the joys of children far outshine the best jobs I've ever had.
