Personal circumstances vary of course, but for me, one of the perks of working from home is that I can help out when my spouse is having a rough day. Obviously, I don't spend all day helping with children, but I can occasionally take a break to comfort a crying child or help with something when my spouse's arms are full.

Also, after the first couple of weeks my young children had no problem understanding that when I'm in my office room I am working, and I can't play. But they do really enjoy seeing me at lunch, which didn't happen when I was WFO.

But again, that's just my experience and I'm sure it's different for other people.
