For future reference, I happened to see your reply to this posting. If you want to pose your own question (vs. replying to another question), ask it separately so you can be sure I'll see it. Now, to your issue. This is not an uncommon reaction in children her age. Just react in a casual, off-hand way, with the exception of when your daughter attacks you. For that she should be placed in time out immediately for five minutes. The discipline has nothing to do with the preference for her father, it has to do with acting in an aggressive fashion.
My 3 year old daughter has recently expressed she wants her father to marry her. She has always had a strong bond with him and still shows signs of seperation anxiety when he leaves. She also at times attacks me when I try to hug or kiss my husband. When he's not expressing affection towards her she crosses her arm and expresses rejection. Should I be worried? Might I add that he was absent for almost 5 months when she was very young, around 5 months?
There is no need to pay attention to whether the therapist is a man or a woman. If he needs male figures in his life you can arrange that via mentors in activities in venues such as the Y, scouts, boys club, etc.
