I actually cope better with night-wakings now, than I did as a younger woman. Maybe there's something about becoming a mom, that frees us from the feeling that we're "entitled" to so many hours of uninterrupted sleep each night.
As a young, single woman, I used to shut off the ringer on my phone when I went to bed, because it was so annoying when people tried to call late at night. Now it's not such a big deal if that happens. Of course, it doesn't happen as much now.
