There’s a reason why people say that babies brains are like sponges — they truly are absorbing so much information at all times! That means that when they see or hear a parent do something, there’s a good chance they’ll try to copy them. This is something that Marcus Angle takes advantage of in the best ways, and he’s happily shared some of the best results on social media.

In one video, Marcus can be seen laying on a bed with his 3-month-old daughter. He sings a little tune, not with words, but with a sound that can only be described as “ahooo!” This sound intrigues his baby, and she tries her best to mimic him. The result, of course, is utterly adorable!

Their little performance only gets better when Dad adds “I love you.” In turn, his little one includes her own “I love you” in the mix, absolutely melting Marcus’ heart — and ours, too!

Watch Marcus and his 3-month-old daughter’s adorable performance in the video below.
