Crying and Complaining

I need some reassurance if there's anything I need to change. Most of the time when I'm in my LOs presence, she wants to be held cries and complains until I have her. If she's busy with someone else, like dad, auntie etc she's pretty content until I show up and she gets moody. If I hold her or nurse she's still complaining sometimes. Is it separation anxiety or is it because I still nurse?
