An adorable baby boy seen struggling to stay awake in his car seat is sweeping the web after more than one million views attributed to his super-human ability to crack a smile.
Smiling toward the camera despite his head falling heavier into his chest, baby Leo fights to keep his eyes on his mother with a twitching smile before realizing his near fall and popping back up, wide-eyed, like a daisy.
With a brief shake of his head, he retains a bright smile and stretches open his eyes before sleep catches up once more.
Like a face scrunching to prepare for a sneeze, he droops losing to slumber before once more catching himself with a delighted smile.
He lets out a cheerful peep in either recognition of his near slip or for his mother beaming across from him with the camera.
But with another droop to his chest, he's near out again.
Pulling his eyes open to acknowledge his mother in farewell, he's nearly down when his final plunge startles him, and pulls his head back up with a similar peep and soft laugh from mom.
'Leo is now 3 years old and I feel so grateful to have 2 wonderful little boys,' the mother wrote with the video on Friday while describing her oldest son of the two who's now seven.
'I love them both so much and I'm so happy that I was able to share this moment with people like you,' she addressed one commenter who praised her displayed affection for her son.
'I had to Uproot a tree to feel manly again,' one commenter wrote after his own view of the video.
