Does anything else the same kind of a reaction?
She may be what we call "needy." Such people feel unloved even when given excessive attention and affection, and crave the attention and affection given to others. The void seems impossible to fill. If this appears to be her problem you might want to seek professional help.
hi everyone, thank you for your reply. no she will say why. it is almost jealousy, but not towards one more than the other. if wife touches me she pulls her arm off, if i touch her, she pulls mine off. my wife started scratching my back and it was like someone killed my little girls puppy. no, not exposed to sexual things. she is a remarkable little girl, its just something inside her freaks her out when we show affection towards each other. of course we would think she would want a big loving embracements by all 3 of us, but it isn't. and it is starting to cause problems.
Has your daughter told you why she gets upset? Annie Brooks suggests a possible reason. Try talking to her about it.
Is there any chance she has been inappropriately exposed to sexual things? I agree with Mark that a therapist might be the next step.
I don't think there is any way of knowing why your daughter is reacting this way until she tells you why it bothers her. If you are very concerned about this behavior, you might want to consult with a family therapist.
