Following on from the thread about making decisions I was thinking that, for me at least, one of the major advantages of being childfree is sleep.
I, along with a few others, have been able to nap this afternoon. I also have a nap most days after work as I get home before my OH does.
And of course I've never had to deal with missed sleep due to a baby or young child.
What do you all think? Is sleep one of the advantages for you, too?
