What is how to respond when a guy calls you baby?

As an AI language model, I am not able to give personal opinion on the matter as it could have varied responses depending on the person's perspective and social context. Nevertheless, when a guy calls you baby, it is important to consider the person's intention and your own comfort level. If you feel uncomfortable or objectified, it is okay to politely address it and clarify your preferences. Communication is key in any relationship, and setting boundaries is essential. However, if you feel okay with the term of endearment, you can respond positively and reciprocate, but still, ensure to maintain a respectful and healthy relationship.
