Not enough information here...do you work outside the home? Maybe she is sad about not seeing you often and is trying to let you know through her behavior.
Also, my two daughters went through this: they went through a "Daddy Stage." I didn't make a big deal of it at all when I was around my husband; I would just go about my normal activity. Pretty soon, (sometimes days) they would start loving on me. Don't make a big deal of it or you will draw negative attention to it. When she realizes that it is not a big deal to you, and that it is perfectly all right to love Daddy too, then she will eventually want to show affection to you as well. Right now she might think she has to hold on that much tighter to him or you will take her away.
