What is can i call my boyfriend baby?

As an AI language model, I do not have personal opinions. However, it is a common way of affectionately addressing one's significant other, and it may also depend on the personal preferences of both partners in their relationship. Some people may feel comfortable being called "baby" by their partner, while others may prefer a different nickname or term of endearment. It is always important to communicate with your partner to make sure you are both comfortable with the terms of endearment used in your relationship.
