My youngest was in the bath tub in the morning and I was cleaning the sinks..organizing hair bows....wiping off toothpaste (you know all that "mommy" stuff we do). I peeked over at my daughter who was giggling "quietly" and notice she had something under the water.
I had my camera right there and instead of giving one of my MOMMY lectures. I just slid right down on the floor and leaned over and listened to all the bubbles popping and bumping together. Yes, bubbles do make noise!
