Children have many milestones in their early years, from their first steps, to their first words, to their first drink from a water fountain.
For one very young girl, she hasn't quite yet grasped the concept of the latter.
In a video posted to YouTube, the little girl figures out the initial part of pushing down on the spout, however, the water continues to elude her.
The camerawoman can be heard cheering on the thirsty toddler, with some laughs, as the intrepid child tries to understand the perplexing invention.
While the outcome of the girl's quest for water remains a mystery, her determination to conquer the confounding fountain is worthy of applause.
We hope the girl was able to achieve her goal of a drink and then took a long nap after her frustrating - yet adorable - day at the water fountain.
