1/ Plan your tasks alongside their activities
Have a list of quick tasks, that can quickly be picked up in moments of calm. Depending on the age of your children, knowing when you will be able to get work done can be hard. But it can be useful to have a clear plan of tasks that need to be done. Then as soon as the children are occupied by an activity then you know exactly what you need to do.
Time can easily be wasted, and that moment of calm can be gone if spend time working out and deciding what to do next. Take the decision out of it and have a clear plan of what needs to be done.
2/ Rethink your working hours
This can depend greatly on the age of your children, but I find that I need to get up early and work until the kids are up, I then need to spend time sorting breakfast etc, getting them settled doing something which will give me some more time to do work, I might get another block of work done in the afternoon, another one after dinner and then once they have gone to bed. Just be flexible, and try different arrangements that helps both sides.
3/ Categorise your tasks between what you can do when the children are around and what need quiet focus
There are some things that you will need to do that can be done when there are interruptions, but there are others tasks that can only really be done when you can focus or when you need quiet. If you need to record videos for a course, or lead a webinar might only be possible when the kids aren’t around but processing emails can be done when there are interruptions.
4/ Don’t worry about using the TV/tablets for a couple of hours of peace
Especially if your working from home is for a shorter period of time such as in the current crisis, maybe factor in screen time that is educational, there are loads of apps/games out that help children learn, and try to balance with some other activities, but if you need to be on a virtual meeting, or you need to focus on a piece of work, putting a film on and getting some snacks out is absolutely fine!
