One couple in Brazil got to witness this firsthand when their baby was born and she heard her father’s voice for the first time outside the womb, according to La República.

Flavio Dantas and his partner Tarsila Rosa were excited about the arrival of their daughter Antonella.

The soon-to-be-dad from Rio de Janeiro talked to his baby every morning while she was growing in the womb but little did he know the reaction he would get when she was born.

Each morning, before he left for work, he spoke to his baby and Tarsila noticed how she would move around when he heard his voice.

When she arrived on August 11, Father’s Day in Brazil, her face was a picture when her dad spoke to her for the first time outside the womb.

Antonella’s face lit up when she heard her daddy and Flavio couldn’t hold back the tears.

“And it is that moment that people forget all the pain and focus on the most sincere smile of all. My princess was born on Father’s Day, ” Tarsilo wrote in a Facebook post.

This beautiful photo capturing such a special moment immediately went viral, hitting headlines around the world.
