There's nothing sweeter than a baby asleep in a mama's arms.
My "baby" isn't much of a baby anymore but fortunately she will still fall asleep in my arms or while lying on my chest.
I was putting Rachel down for a nap recently and she was so tired that she didn't even want me to read to her. When she gets sleepy, she gets clingy and she will usually say, "Mommy. I want you." and that's my que that some I'm about to get some snuggle time with my little girl. If I snuggle up with her in the glider and she falls asleep, I have been known to fall asleep right there with her. I did on this day but woke up enough to motion to Stuart to get a picture of Rachel's sweet face as she slept.
There's nothing sweeter.
