Even before their babies are born, mothers express their excitement by talking to them while they’re still in the womb, eagerly awaiting their arrival. Once their children are born, they bring instant joy to their parents’ lives.

Parents often speak to their babies as if they already understand, and experts say babies are more attuned to sound than we think. Though they can’t yet form words, babies respond to the familiar voices around them with coos, cries, and smiles.

One heartwarming example is baby Willow, whose mere presence melts her mom, Ariana’s heart. Ariana sings “My Girl” to her precious daughter, and in return, Willow responds with adorable coos and smiles, as if complimenting her mom’s beautiful voice. It’s a simple moment, but it captures the deep connection between mother and child.
