Crying

I was rereading, The New Father the other day, and I came across a passage that said something like:

Your new baby will cry a lot, an average of three hours a day.

If my child was crying three hours a day (or even one hour), I'd know that something was terribly wrong. Do other people's babies -really- cry that much?! That's insane, how could you handle that?

Marion and Henry cry, maybe 5 minutes a day, total. I know that carrying your child a lot (which Keleigh and I do) really reduces the crying, so I guess that's helping, but three hours...that's crazy.
