I only write blog. To answer your original question, kids are great stress reliever. I work from home and often get irritated by their unwanted shouting and screaming but then I don't work all the time. I do give them time, eat with them and play with them. For blogging/side projects etc it does not take much time, specially if you are organizing things around you.
