One of the most difficult things about working from home is keeping your kids busy, so that you can get your job done. Now if your kids are older, like mine, you make it clear you're not to be disturbed, close the door, and you're good. But if your kids are younger, you have to be a little more inventive. If you don't keep small children busy, there's a very real potential for disaster. But there are some things you can do to increase the probability that you'll actually get some work done.
The first - and by far, the easiest - hire someone for a few hours each day to help out with the kids. Young teens, especially those who aren't old enough to get a real job yet, love this kind of opportunity to make some extra cash. You'll still be nearby for the real emergencies. But your helper can feed them a snack, play a game with them, help with homework.
If this is not an option, either because you can't afford it or because of a lack of potential candidates, make your children a busy box. Put in art supplies, games, books, things that will keep them occupied while you work. Remember to alternate the items in the box, so they don't get bored with it. For small children who still need to be within eyesight, lay out a blanket in the corner of the room, give them the box, and get to work.
It's really important to make it clear to children, once they're old enough to understand, that what you're doing is important, that you're not just playing around on the computer or phone. Give your children a signal, so they know when you're done by turning off the computer, stretching, giving them a big hug. This lets them know mom is available now. This will help them to recognize the difference between your fun mom mode and your work mom mode. It also teaches them to be patient. Because they know when you're done, they'll have your complete attention.
