That is the sound coming out of my 8 month old. His Gramma (via FaceTime) and I just witnessed him lay down in the middle of the floor and float away into a peaceful, hopefully long, nap. If you've never witnessed a baby do this you are missing out! It should be named one of the wonders of the world!
When I get the rare chance to see Tucker do this I feel as if I've played with butterflies or touched a cloud. It makes you so happy. It also makes me want to nap TOO! :)
XO, Abby & Tucker
