Hi, I'm a single father and have a 3 year old daughter who's going on 4 in December. I split custody with my daughters mother. I Have From Saturday up til Tuesday, and her mother gets her Tuesday til Saturday. I seem to be noticing a pattern with my daughter. She tends to play well with others for the most part and at times gets very territorial with her toys and what not with other kids.. She says the word "mine" and it gets very annoying, because it makes me feel bad for her other friends who come over to play with her and she doesn't share sometimes. She also seems to get angry at times and sometimes doesnt listen. It seems like she wants to always get her way. Now I do the whole 3 minute time out rule and I notice she gets angry with that, she"ll stomp her feet on the floor, I tell her to please stop, and she tends to repeat that behavior a few times, then she settles down. My niece who is 4 years old has worse tantrums than my daughter and there isn't a day that goes by that there isn't some sort of disagreement between the two of them. I feel as if she's picking up some bad habbits from her. My daughter tends to play pretty well with my girlfriends daughter, although there has been some instances where if her daughter would want to sit on my daughters bed to watch elmo with my daughter she would tell her, "No My bed" ad throws a fit, and I can understand that yes its her bed and all but still, i think they both should be able to sit and enjoy watching elmo together without any issues. My daughter has also thrown a book at her and that is uncalled for. I dont approve when my daughter gets aggressive, it's embarrassing and makes me feel like the other kids dont want her around because of her actions. I am doing the best I can to raise her right and to have morals.. to be polite and courteous to others. Im all for discipline but am against spanking. What can I do to better the situation. People have noticed her behavior and it makes me sad. Please help.
