Rocking baby to sleep

I just spent an HOUR rocking my baby to sleep. I started off a little annoyed that she was just staring into space and didn't seem that sleepy...but then as I was rocking in the dark I started thinking about when I'm old and I thought about how much I would ACHE for this moment..and how very very lucky I am to be able to rock this sweet baby girl to sleep. I rocked her until she was deeply asleep and then I placed her in her crib and it was so special, so precious, and it will all be over before I know it. I don't want her to grow up...I wish it could all go in slow motion.
