Once upon a time, in a world full of magic and mystery, lived a bright, fiery-haired girl named Yang Xiao Long. One day, she was tricked into drinking a potion that turned her into a baby.

She found herself in a baby's body, but her mind was still that of an adult. Yang tried to act her own age, but found herself unable to do so. She cried, giggled, and played like a real baby.

With every passing day, Yang began to enjoy her new life. She was renamed 'Sunny' and given a teddy bear that she loved dearly. She was a happy baby, and didn't want to grow up anymore.

One day, the teddy bear spoke to Yang. He asked her if she wanted her friends to join her in being babies. Yang, being a joyful baby, nodded in agreement.

The first to become a baby was Blake. She turned into a pink-loving baby, who adored being cared for. Blake was renamed 'Blossom' and became a delightful addition to the baby family.

Next was Weiss, who was trained by Yang and Blake to be a baby. She received a new name, 'Snowflake', and a cute stuffed bunny. Weiss soon forgot how to be an adult and became a happy baby too.

The last one to join the baby family was Ruby. But she didn't become a baby, instead she grew older and became the mother of the others. Ruby embraced her new role and took care of the babies with love and joy.

As time passed, Ruby started to worry. She loved her baby friends but knew that they couldn't remain babies forever. She missed her old friends and the adventures they used to have.

Ruby decided to find a way to turn her friends back to their original ages. She searched for the potion recipe, hoping to reverse its effects. She knew it wouldn't be easy, but she was determined.

After days of searching, Ruby finally found the recipe. It required rare ingredients and a full moon night to prepare. Ruby gathered everything she needed and waited for the perfect night.

The night of the full moon arrived. Ruby prepared the potion with utmost care. As she finished, she looked at her sleeping friends with a heavy heart. She knew she was doing the right thing, but couldn't help feeling sad.

The next morning, Ruby gave the potion to her friends. One by one, they transformed back into their adult selves. They were confused at first, but Ruby explained everything to them.

Yang, Blake, and Weiss were surprised, but they thanked Ruby for her effort. They were happy to be adults again, but they also missed their time as babies. They promised to cherish the memories they made together.

From that day on, the four friends continued their adventures. But every now and then, they would take a day off to reminisce their baby days. They would laugh, share stories, and enjoy their time together.

The story of the baby bear and her friends became a legend in their world. It was a tale of friendship, love, and the joy of childhood. It reminded everyone that no matter how old you are, you can always find happiness in the simplest things.
