You've heard of the "womb noises" CD for newborns, right? It supposedly mimics the heartbeat heard by baby in utero.
Well, wrap up your little bundle, place them in a gently rocking swing and let them fall asleep to "Digestion Sounds of Pregnancy."
I'm pretty sure my babies hear that way more often than they the 'whoosh, whoosh, whoosh' sound that we all think is prominent.
Oogle Loogle Loo... bloop.
Ahh. That's nice. Good night.
PS - Babies are approx. size of a bell pepper. Red are my favorite.
