Everyone remembers when their child says their first word. Typically, around 12 months old, a child will say the typical ‘mama’ or ‘dada’. But what happens when it’s a 3-month-old baby speaking a complete sentence?

On TikTok, a family’s out-of-the-world experience has gone viral, and along with it, the emotional reaction of a sister proud of her brother. Mekeia (@foxondemand) shares moments from her life, and when she captured this crazy moment it instantly went viral, with more than 16.7 million views.

The video starts with a baby babbling and a young girl who is chatting with her baby brother. You see the young girl, holding the baby’s fist and she says, “I am 2 months.” Mekeia says, “(He’s) 3 months, girl.” The little girl than says, “Say, ‘I am 3 months.”

And then as if it’s nothing out of the ordinary, the baby says, “I am 3 months.” The daughter runs toward Mekeia, both stunned. The voice is a sweet baby voice, but it’s easy to hear the words he spoke. Mekeia rushes to the phone and calls a friend.

She then tries to get the baby to say, “Hi, Val,” and then “Hi, Quentin.” It takes a moment, then in a tiny baby voice you hear, “Hi, Quentin.” The love and emotion of the moment has his sister crying and giving him kisses and cuddles.

Her TikTok comments were full of people amazed. One person wrote, “That’s crazy! Wowzer! I’m sure I’d be shocked. I talk to my baby a whole lot every day but he isn’t even close to saying anything that could be perceived as a word. Haha. But I’d love it if he could tell me he loves me :)”

While the internet is amazed, it turns out there are a few reasons why this may not be as surprising as it seems. The Raising Children Network notes that between 3 months to 12 months, a child’s vocal development is constantly growing and changing. The network also said that parents will notice the baby testing his or her voice by constantly babbling and cooing. They also tend to play with sounds, “copying (and) putting (them) together.” Also, some studies have indicated that it is possible that younger children with older siblings may talker sooner than typically expected.

And speech therapists agree, it’s all normal. “Echolalia (when children repeat speech) is a normal part of child development. As children learn to talk and understand words, they imitate, copy or echo the sounds and words they hear,” said Claire Smith, a speech and language expert.

Regardless of how the baby managed to speak, it just goes to show that kids are listening to their parents and siblings, even when they are tiny babies. But for now, the internet has its own opinions ranging from “he is a baby genius” to “next thing he’s writing emails and making appointments.”
