My relationship is confusing. I am the only mommy my daughter knows as her mother left when she was 1, she is now almost 5. I came into the picture around age 2 1/2. I have a hard time w/ discipline, she doesn't take it well from me, not that she is defiant, she goes to timeout, and does what I say. But when I talk to her she hums, she won't look me in the eye. She is an anxious child, she has oral nervous behaviors, and only reacts to me when I'm super nice, if I even tell her to take her shoes off the couch she will then go hide in the corner and eat the skin off the bottom of her feet, or chew her hair etc. She says, I guess you just have to tell me how to do everything mommy. My husband blames me for her nervous behaviors, he tells me I'm too hard on her, as I have a biological son the same age, he says I'm not as hard on him. I discipline them the same way, and even though he sees that, he is just so blinded by the fact that we both see his exwife's face in his daughter. This has been talked about once before a long time ago, and he said it again last night, only this time he said it in an accusatory way. She manipulates, and we fight about her, usually he is defending her bad behavior and questioning my discipline in front of her. Then she'll cuddle w/ him. I told him to discipline when he's home, an example last night: she got a sharp knife she knows she is not to use, I feel dangerous things deserve at least a timeout, he said to her "do you use sharp knives?" she said no, he said "ok", and she walked away. I looked at him and he said, "well hopefully she won't do that again". I can't possibly just let her do these things and give her no direction, I feel kids need discipline. I can't say that I'm not immune from yelling at both of them in the past, but I have been working on it, and we are in family therapy to deal w/ this, and I have been learning ways to cope w/ myself, and this is under control. My husband is pretty un-available in many aspects of my life, so it is a difficult situation. Maybe it is my fault. Does anyone have any suggestions?
A little more info: my son is only months younger than her, and they have an older sister. This may be a consideration into behavior, and emotional issues of middle child or something, I don't know, I just love her and want her to love me too.
