Hello, could someone please help me with the following issue. My partner and her ex have a little girl who lives with her mother and myself (100%) of the time with a night at her dad's maybe once a month. When she was born they agreed not to immunise ( immunisation) as both were against it. She is now 3 1/2 years old and the father wants to immunise her as his new partner wants it done. Her mother is still very against it and now the father is saying he is going to go and get it done when he has her over anyway. How do we stop this prior to it happening? Are there legal repercussions under family law for him doing this? Thank you to any one who can help with this question.
