Listen: Baby Says ‘Mama’ In ‘Almost Demonic’ Way

Hearing a child's first words is something every parent looks forward to. For two parents in Ireland, however, the experience was not exactly what they were expecting.

In a video captured Sunday by the baby's mom Maiken Woll Eide, she and her husband Julian Brophy were enjoying a meal with their 16-month-old son Aiden James, or AJ, at their home in Wicklow, Ireland. Baby AJ was happily sitting on his father's lap while munching on berries when his mom asked if he could say "mama," ABC News reported.

Eide was holding up the camera, waiting for that special moment to be recorded when her son would finally say the magic word. To their surprise, AJ did say "mama" but not in the way they anticipated it.

Baby Aiden said the word in a low, almost growling voice that Eide described as sounding "almost demonic" — causing both of his parents to burst into laughter.

The little toddler said "mama" a few more times, with the same growl that shocked his parents, before going back to eat his berries.

ABC Philadephia shared the video of the hilarious moment on YouTube.

"We laughed so hard, and he's still saying 'mama' like that," Eide said.

Eide told ABC that little AJ is now on his way to learning how to say "papa" — something they are looking forward to hearing hopefully in a more adorable and less "demonic" way.

Babies are known to be able to understand simple, one-step requests at around 12-18 months of life. According to WebMD, it is during this stage when babies begin to utter words like "mama" and "dadda."

By the time babies reach 18 months, however, parents can expect them to already be capable of pointing at objects and repeating words and sounds around them.

By the age of 3, babies' vocabularies are expected to expand significantly. It is also during this age when their understanding of symbolic and abstract language begins. Feelings like "sad" and "happy" are understood and concepts such as "now" and "in" start to make sense, WebMD noted.
