You can call it whatever you want.

When you have a baby, people always ask you, all concerned, how the baby sleeps.  I tend to answer something like, "oh, fine" or my favorite "you know, just like a baby".  The reality is, neither of my children has been a particularly great sleeper - if you define sleep as going to bed easily at night, then not being heard from again until the morning.  But that's OK.  It ends.  Pea is actually a very sound sleeper now at 3.5.  On the other hand, her baby brother woke up the other night at 11PM and all he wanted to do was wrestle.  I tried to calm him down, soothe him, rub his back, and he was like, kick!  punch!  lay on Mama and pin her!  roll around!  If there were ropes around the bed, he would have tried one of those moves where he bounces off the ropes, I'm sure.  Babies are funny.

Despite its title, Call It Sleep is not actually about sleep very much at all either.  The story follows Davy, a little boy, a recent immigrant to New York in the 1900s.  It is all about assimilation and growing up, learning the new city, new language, new customs, etc.  I really enjoyed this book - it was long and some of the language was hard to understand at times (the author uses a very phonetic method of showing the different accents that people have, and it can be confusing and hard to understand what people are saying) but I really did like it.

Even if it isn't about sleep.  Not that I'm getting big chunks of sound sleep anyway.
