Hi I'm new on here, and I have heard a lot about mumsnet, I thought I would ask for help because I don't have much experience of what my friend is going through. At the moment she is in a desperate situation. I thought I would ask for some help please.
My friend and her ex partner will have to go to court to obtain a residency order for their daughter. I am asking really for practical help to help my friend deal with her child's behavioural issues during this time.
For example, my friend went to collect her child last night after a visit to her Dad, but the little girl did not want to come home. She is only 7, and had a big tantrum!!!! Her dad did not help, he just said 'this is what she wants I'm not making her go' and then started to argue with my friend, and he is very intimidating, she is scared of her ex. So, my friend tried to pick up her daughter so they could leave, but the little girl just screamed, and started kicking and fighting, so my friend had to let her go. Over an hour of persuasion had passed, it was almost 10pm, and the tantrum escalated. To end the stress, my friend agreed to leave as long as her ex brought her home this morning instead. He was meant to have taken her home last night, but instead insisted that my friend had to pick her up, I feel that if he had taken her home as agreed, then the situation could have been avoided.
How do you deal with that kind of challenging behaviour? the child knows she can play up and get what she wants, as her dad never says no to her. When her mum left, the little girl was happy as she had her own way. The trouble is, she was meant to go back to school today, so she was meant to go home, now will miss a day and the situation is much more stressful than it has to be. How do you discipline children in those situations? this happens after every visit, and every time she goes past her ex's house on her way to school. It's very distressing and my friend is really worried about the effect on her little girl.
Her daughter is too young to understand what is going on and is only reacting to the situation, but unfortunately every time she tantrums her Mum has to give in, so the tantrums are getting worse and she is getting very confrontational. Shouting, kicking, hitting 
I have a son, and I can deal with his tantrums, but I'm not in that situation so I don't know what would work. As my friend is alone and does not have many friends or family nearby, I was wondering if she should ask a social worker for support? I know people fear social services, but my experience of them when I needed an operation and my son was a toddler was excellent, they organised child care for my family and were very supportive.
Any advice is greatly appreciated, thanks.
