Sun and Moon were brought home amidst celebration. Eclipse, however, was not amused. With a scrunched up face, he watched the twins from a corner.

"Eclipse, meet your brothers, Sun and Moon," his mother cooed, gesturing towards the twins. His father was grinning ear to ear. Eclipse just frowned.

The babies demanded constant attention. They slept at odd hours and mostly cried. Eclipse was continuously disturbed by the incessant noise.

One night, driven by curiosity, Eclipse crept into their room. He saw Moon's tiny hand clutching Sun's. His heart softened momentarily.

At breakfast, his mother gave him a gentle reprimand for sneaking into the babies' room. Eclipse stared at his cereal, his cheeks coloring.

Eclipse missed his quiet, peaceful life. The one where he was the center of his parents' world. He felt lost, replaced, and hurt.

Listening to his parents' laughter, Eclipse felt his heart ache. "Why are they so happy?" he wondered aloud, his eyebrows furrowing.

As weeks turned into months, Eclipse tried to ignore the twins. But their presence was undeniable, and his disdain was hard to hide.

One day, he saw Sun giggle. It was a soft, airy sound, like wind chimes. Surprisingly, Eclipse’s heart warmed a bit.

His mother noticed the change in him. "Eclipse, do you want to help me bathe the babies?" she asked. Eclipse nodded tentatively.

Bathing the babies was an adventure. Eclipse felt a strange sense of responsibility. He even managed to make Moon giggle.

Eclipse started feeling a bond with the twins. He noticed their individual quirks - Sun's giggles and Moon's fascination with everything around.

His parents were delighted at this change. "Eclipse, you're a big brother now," his father said, ruffling his hair affectionately.

Eclipse began viewing the twins not as intruders, but as companions. He started playing with them, sharing his toys, and even his bedtime stories.

One evening, he found Sun crying. Moon, too, had tears in his eyes. Eclipse quickly comforted them which stopped their tears.

"Eclipse is a good brother," his mother praised. "Of course, he is," his father agreed, patting his back. Eclipse smiled.

Eclipse became their protector. He would tell them stories, sing lullabies, and make funny faces to make them laugh.

The twins adored Eclipse. Their eyes followed him around the room. If he left, they’d cry. This made Eclipse immensely happy.

"How did I ever dislike them?" Eclipse mused, cuddling the twins close. His heart filled with love and warmth.

His parents were thankful for the bond the brothers shared. It made their life easier and filled their hearts with joy.

Eclipse's initial jealousy had transformed into profound love. He realized that siblings were not threats, but friends for life.

Some years later, Eclipse sat with Sun and Moon, excitedly planning their next adventure. Being big brother was not so bad after all.

Eclipse learned the true essence of being a big brother - helping, caring, and wanting the best for his siblings.

He has grown, not just in age but in emotions. His journey of being a jealous older brother to a loving one was beautifully transformative.

Today, Eclipse, Sun and Moon are inseparable. They share secrets, dreams and even friendly bickering. Their bond is admired by all.
