3-month-old baby shocks mom and sister by repeating full sentences. It may have a name.

Babies can't talk. This isn't something that needs to be studied and researched, it's a pretty common fact that humans have. The reasons babies cry is because they can't talk to tell us what they need, at least that's what the general understanding has been for centuries. But what if some babies could talk and we simply haven't been exposed to them because the world is so big?

Thanks to social media, the world has gotten a whole lot smaller when it comes to being able to take a peek into other people's lives. This means we get to be exposed to things that may otherwise gone unseen. Mekeia, a mom of two recently uploaded a video of her 3-month-old son talking. Not the cute baby babble that we like to call talking, but repeating actual short sentences.

Mekeia was recording her daughter playing with the baby when they captured the moment on video.

The little girl holds the baby's face and says, "say I am two months," before Mekeia corrects her, "say I am three months," the little girl pipes back up. Clearly the baby was trying to join in the conversation with what was expected to be baby babble when the mom instructed the older child to let the baby have a chance to "talk." It was then that the baby shocked everyone by sounding like he repeated the same phrase.

The two are visibly and audibly shocked not wanting to believe the baby actually repeats what the other child says. Mekeia is on the phone with a friend when the entire thing happens. Presumably thinking this is a fluke, the mom attempts to put the phone up to the baby's mouth. When he just babbles, she tells the baby, "say hey Bam." Nothing. Just more babble and drool.

Just when you think your ears were playing tricks on you, the baby does it again when the mom tells him to say, "hey Quintin." Clearly the baby still sounds like a baby but you can clearly hear him repeating the sound and cadence of the words so much so that it sounds like he's fully saying the words. His older sister is overwhelmed with emotion and begins to cry while Mekeia seems to be so shocked that she begins to laugh while the person on the phone is just stunned into confusion.

People in the comments were eager to jump in with exclaiming the baby is a genius with one person writing, "he is a baby genius start showing him math problems."

Another person jokes, "next thing he's writing emails and making appointments."

"Talking so clear would scare me sooo bad he's so intelligent," someone writes.

Others explain the phenomenon with a condition called echolalia. "Echolalia 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. Over time, a child usually learns to talk by connecting new words together to make unique little phrases or sentences,” according to Speech and Language Advisor Claire Smith when interviewed by the BBC .

While echolalia can be a sign of autism, that's not always the case. Many kids grow out of it by the age of three and continue their typical development.
