It may seem crazy to some, but kids aged 2-5 can actually learn things and be taught that when a parent is in their office, they are not to be bothered. I have a 2 and a 4 year old at home, and they know what my office is for.

That being said, their games in the other rooms of the house are occasionally pretty loud, but is it really worse than an open office?

Yes, we watched my nephew from birth to just over 3 years old for 16 hours a day while I worked. He learned that if the door was closed it meant I was busy. At times when I had on music he knew he could come in and sit and listen while I worked as long as he didn’t talk.

He grew up that way though, so YMMV of course.
