Boo would probably interact with the baby monster in a very gentle and affectionate way. She might hug it a lot and try to communicate with it using her own unique baby language. Since she's a child herself, she would likely see the baby monster as a new playmate and would share her toys with it.
It could be about Boo using her experiences in the monster world to make a difference in the human world. Maybe she becomes an advocate for better understanding between humans and monsters.
A possible plot could be that there's a baby monster that is scared of everything in Monsters Inc. Boo, who has experienced the monster world, takes it upon herself to show the baby that there's nothing to be afraid of. She introduces the baby to all the friendly monsters she knows. Sulley and Mike are a bit skeptical at first but soon see how Boo's kindness is helping the baby grow braver. As time goes on, the baby becomes more confident and starts to explore the world on its own with Boo by its side as a guide.
Monster Inc is purely fictional. There's no real-life basis for it. It's all about bringing to life a colorful and imaginative world filled with monsters and their adventures.
