Baby giggles are some of the best sounds in the whole world. There's something about the innocence and joy in an infant that truly becomes contagious. Take this sweet baby and his grandma as they play the most adorable game of peekaboo together.

At first, I thought the baby was going to sleep but suddenly, it popped up with a smile and that's when the laughter started. Once the peekaboo began, there was no stopping the fun and smiles. Every time he puts his head back down, it pops back up ready for another round.

It's obvious these two love each other so much and it makes my heart so happy to see them interact. And after all those smiles and laughs, I cannot help but to smile too. What about you? Don't you just love baby giggles?
