Well, I really did mean that everyone is different! Don't let me or anybody else keep you from doing what is right for your family, which includes you, too! What you yourself need is also very important.
I think I mentioned earlier that I am old--we married relatively late, and then it took 12 years after we married to conceive the first time (with lots of boring appointments with fertility managers and so on--and in fact didn't get pregnant until after we'd given up on all of that process)--so I had a long, long time to have time for me, and so probably don't feel the same kind of need now to have regular breaks from my kids as a younger mother would. Plus I'm so childish anyway that I just really have a lot of fun with my little comedians!
You do what's best for you--and don't worry, nothing's written in stone. Changes can happen if they need to.
good luck
