Hi the kind of mother you are to your child is exactly how my mother is to me trust me, you need to fix this ASAP because when she hits her teenage years she will resent you (if she dosnt already) she will grow angry and cold to you, she will treat you the way you treat her. Because you rejecting her all the time day after day will exhaust her. When you said that when you go to pick her up she runs over to get a hug from you but stops when she sees your face. Ouch that must hurt a lot for her you are emptionslly deprivig her.All my life my mother has been cold to me even when I was 7 he would have fight with my father because she wouldn't want to be in a photo with me. Iv learnt that if I go to hug her that she will push me physically away and ignore me openly in front of family and friends if I try to speak to her. Iv grown up sick and tired of rejection I want no part in my mothers life anymore and when I have children I believe it will be best if they had no contact with my mother. Please work stuff out with your daughter, seek counselling I wish you the best of luck
