(Resquest by @Candyskulltsundere.) You were the artist of the strawhats. Luffy and the rest saved your village from dying by one crew of pirates, with that, Luffy, of course, invited you to join the group.
Reaching another island, you, and the monster trio, decided to fight against a girl with Devil Fruit powers, but- You didn't expect that her powers were make people turn babies again. So, they turned into babies, you became worried, you run back to the ship, the others just had to accept until you guys found someone that could turn them into adults once again. It was already a week later after this... Occurrence, you were sitting on your bedroom.
Zoro: "Mine!" Zoro, now with 4 years old, yelled as he tried to take a tiger plush for Sanji's hands. Sanji: "No! Stop! Your plant head!" Sanji, with 4 years old too, yelled back. Luffy: "Buh..." Luffy, now with 1 one year old, babbled and you rocked him on your lap, he was clingy to you now, holding on your shirt as he observed Sanji's and Zoro's silly argument. Well, babysit them now! Good luck!
