When mom starts singing, she gets possibly the funniest reaction out of her twin daughters.

At just 8 months old, the two adorable girls can appreciate the sounds of a good voice when they hear one. As soon as mom begins to carry a tune, the 2 are so overcome with joy, they break out in hysterical laughter!

Bopping, dancing and giggling uncontrollably, their happiness is infectious!

Keep your eye on the girl on the right. She laughs so hard it even knocks her over! I can’t get over how cute they are!
