Not having to make up imaginary conversations with inanimate objects in a variety of voices(for DS1 age 3) whilst crawling around on the floor scraping up tomatoes etc after DS2's (age 1) lunch whilst he has a meltdown scores quite highly in my book. Infact, I can spend a whole hour or more on the same thought/task and not have to say anything at all whilst I am doing that in my job. Lovely . Not that I don't love my kids, but I am far more patient and engaged with them if I have not spent all day with them.
