Sleeping Close to Mommy

Faith is like a cat...
When we're out, she'd sleep for as long as 2 hours if I have her in this position, snugly wrapped in a sling, close against me. When she's placed in a pram, she'd wake in half an hour -- standard!
Many say I spoil her...I don't care much about that comment. Nothing cheers me more than seeing her sunshine smile when she wakes from a good nap! :)
Afterall, how many more months can she sleep in my arms like that until I can bear her weight no more?
