As an adult, being the center of attention as people sing «Happy Birthday» may be tough — what are you supposed to do for the following 30 seconds? Where should you lay your hands? Is it okay for you to sing as well?

Rhett Flener, three years old, has no uneasy feelings. The lovely boy celebrated his third birthday on January 1st, and his parents shared a video that will melt anyone’s heart.

Rhett was born with Trisomy 21 (Down Syndrome) and also had to have reconstructive bowel surgery within his first few months of life. Since then, the tot has been in and out of the hospital with illnesses including pneumonia. You’d never know he’s had so many medical issues, though, because the joy in his eyes is impossible to ignore!

Rhett seems fascinated with his birthday cake in the video provided by his parents, especially the «3» candle. Then, when his parents begin to sing, a huge smile spreads across his face, followed by what can only be described as gleeful laughter.

Rhett’s parents take his cake closer to him and tell him to blow out the candle after the song is finished. He gives it his all and eventually blows it out (with a little help from Dad).

Given Rhett’s enthusiasm for the candle, you’d think the toddler would scream as the flame went out. Not with this youngster. He became even more ecstatic and celebrated his accomplishment with his palms in the air.

In the video’s caption, his mother said it best: «My heart just can’t handle it!!!!!!! «He’s so tickled!»
