No matter what kind of day I’ve had, the sound of a baby laughing is sure to make it all better. You just can’t hear that sweet giggle without smiling yourself! It also takes so little to make little ones smile and laugh, and it’s such an adorable reminder to take joy in the simple things. Today’s reminder and adorable video comes to us from America’s Funniest Home Videos, sharing the too-cute reaction of a baby whose dad is tickling her feet with, of all things, air. Just watch, and smile.
