When Alder, a 4-month-old baby, sang with his mother, he won the hearts of many. Doug, Alder’s father, dropped by to teach him some chords, and when little Ader began singing, ohn grabbed a nearby camera to catch the scene, according to ohn, who posted the video.

When Annie began singing, Baby Alder seemed to be awestruck by her mother’s voice. Alder began to open his mouth in an attempt to sing along with his mother. He was imitating Annie’s facial expressions while she sang, and he even tried to perform the song himself.

Annie said, “The whole time I was singing, he was -” then she showed Doug what their baby was doing. “It was so cute!”The Cognitive Neuroscience Society says that “these songs (lullabies) can increase a little one’s attention and displays of positive emotion toward their mamas.”

I See Me also said that “Singing to infants and babies strengthens that bond between parent and child. And it heightens and regulates their sense of awareness and attention.”Watch how baby Alder tries to sing along with his mom in the video below.
