Baby keeps crying

Natalie

My baby girl is so fussy and I don't know what's wrong! I can give her a nice warm bath, clean diaper and feed her and she's still fussy. Idk if she's just constapated or not. She hasn't pooped in 2 1/2 days. Is that normal? Any suggestions? I've been putting a small dot of Karo syrup and it's not helping.
