Is it bad if my Girlfriend treats me like a Baby?

I didn't notice till my friends pointed it out but she's always kissing me, cuddling me and pinching my cheeks. She literally calls me her little baby and talks to me like I'm one, even in public in front of my friends.
And she'll say stuff like: "You're so cute/adorable" or "I could just eat you up".
plus she's a lot taller than me.

I don't know if I'm overreacting. Is that normal?
