Kids at home interrupting your work?
Try this . . . (works best with school age children)
"The Pomodoro Technique is a time management method developed by Francesco Cirillo in the late 1980s. The technique uses a timer to break down work into intervals, traditionally 25 minutes in length, separated by short breaks. Each interval is known as a pomodoro, from the Italian word for 'tomato', after the tomato-shaped kitchen timer that Cirillo used as a university student." Wikipedia
Set up activities for yourself that can be done in about 25 minutes. Sometimes you can do several things in that time and sometimes you can only do part of a project in that time. If you have calls, this may be harder but you could try 30 or 45 minute intervals.
Next set up activities for your kids to do in that amount of time. Explain that they will be working on their activity until the timer goes off and you will be work on yours and then you will take a break.
It won't be easy at first - don't give up. Depending on the age and activity level of your kids, you'll have to adjust the time.
When you take a break, do something fun and active. Turn on your favorite tunes and dance. Find a yoga or other exercise video and do that together. Take a 5 minute walk around the block.
