Nosy and bossy, but also fun-loving and supportive — that is what a sister is all about. Having a sister can make life easier, smoother, and funnier. Depending on her quirky behavior, you can call her with an interesting nickname. For instance, you can call her ‘mommy 2.0’ when she behaves like your mother or tease her by calling her ‘babyface.’

But remember, nicknames should not be offensive or put down the sister or any other person. They have to be agreeable to the positive quality of the sister with mutual agreement from her.
