What does it mean if a girl you like starts calling you boo and baby?

What you are really asking is whether or not you should protect your heart from this girl. Last time you called her boo, she responded positively calling you baby. What you're doing is called: flirting. :)

Keep building the momentum. Flirt. Talk more. Make her laugh. Share more time together. Go out for coffee. Go see a movie. Enjoy your friendship and be the friend you want to be to her. If you want to be a boyfriend, start acting like one slowly over time. One day she will stop and ask you, "so, where are we at?" and you can tell her "you're the girl of my dreams and I want no one else but you."

But until you reach that point, keep up with the baby steps. For now, call her boo. Let her call you baby. Push the boundaries. Have fun. Each step you take will help you gauge her interest. There are never absolute answers: yes, she likes you or no, she just wants to be your friend. Women want to FEEL that connection. She feels comfortable enough with you to call you baby and that's a good sign.

Honey boo boo child

Means that she's probably more interested in you than just being friends. Pet names are often a way to indicate a higher interest.

well in her mind she's thinking that you guys are together as in couples or it just she calls you that for fun. my guy buddies call me boo and baby or even babe but I don't mind even though I'm not into them or anything.

Shes ready for a swat

Depending on how shes saying it, you could just be friends, but I'd say it sounds like she likes you too. (:
