Night watch

I've just put Lisa back to bed.
The crying started at around midnight. I decided to give her an opportunity to cry herself back to sleep. But after 30 minutes, she was still going strong, and was probably wondering where her loving parents were. So she started walking down the hallway, still wailing. I intercepted her just before the family room and picked her up.
As usual, the loud crying turned into heavy sobbing and then she was asleep again.
And once again, I felt guilty for letting her cry that long.
But how else are we going to break this habit of the midnight howling?
What's the phone number of that Super Nanny?
