Hello Vette06,
Here is a brilliant resource for helping you parent more confidently with a wife who has BPD. It provides lots of information on what and how much to tell your children, and how to equip them with tools to protect them emotionally from their mothers illness.
Lessons for members who are Parenting & Co-parenting with a pwBPDIn choosing to stay it is important that our children understand and learn how to navigate the parent with BPD dysregulated behaviours in the same way that we have.
I started equipping my son with age appropriate skills and information when he was 5. He will be 8 next month. He is a grounded, well adjusted little boy. He understands his father is mentally ill and that nothing he has ever done or will do has made his father sad, angry, upset or ill. He also understands that sometimes his fathers behaviour is not normal or usual behaviour because of the mental illness. Our son understands that he cannot make it better for his father when he is unwell, and that it is important to continue with all the things he loves despite his fathers illness.
It is really important not to excuse our SO's behaviours as just upset or explain them away to our children. Being clear with our children when a parent has mental illness will help them understand that this is not usual in other families. They need clarity and age appropriate understanding to ensure that they do not internalise their family dynamic as typical. It is not typical. Help them understand what happens in a typical family and then we can validate that their family set-up can be upsetting and difficult.
There are lots of strategies and help that we can use to better protect our children. Remember we are the well parent and can and should intervene if we feel our children are being exposed to things that are not good for them. It is important that they are allowed to be children for as long as possible.
