Well whoever said that girls are just fussy either has bratty girls or only boys.

My daughter and all my nieces were sweet, even-tempered babies who were fussy just as much as any other babies - when they were told no, or they fell, were teething, tired, too hot, hungry, etc.

But I'd say if its to the point that she's constantly unhappy, and always has been this way, I'd ask the doctor what they recommend when you go back.
