My borderline adult daughter has worn me out.

[Foolingmyself]

I have not posted in well over a year. My daughter who last time I was posting was pregnant and engaging in very harmful behavior had come back home to live. For about ten months after she had the baby we were doing okay and I thought the worst was behind us. A few days ago I noticed a change in her behavior, she was becoming irritable with the baby, wanted to go out and left her breastfed baby with me for eight hours. The baby was beside herself wanting her mother’s breast. Of course I told my daughter to come home. She got mad and kept the baby in her room for two days. My daughter’s other response to this was to abruptly wean the baby because “summers coming and I want to be able to go out”. The baby has been crying and is pulling her hair. She indicated to me that she planned on leaving the baby with me overnight in the future because she wanted to enjoy the summer. She also said that she expected the man she dated on Saturday to be calling her soon and that she wanted to be available. This morning started off okay but ended in the splitting episode to end all splitting episodes. She called several people to complain that I am a bad mother. It ended in her calling her grandfather to come and rescue her from me. Which he did. I’m at the point where I can’t keep dealing with her. I know she is sick but she is also horrible to me. The badmouthing today was horrific. I’m not going to be a pin cushion anymore. I think this is it. Let someone else step in. I’m exhausted.

Our objective is to better understand the struggles our child faces and to learn the skills to improve our relationship and provide a supportive environment and also improve on our own emotional responses, attitudes and effectiveness as a family leaders

We're so sorry to hear this update, but also it's not that surprising.  Those who have people with BPD traits (pwBPD) in their lives - including their children - are often faced with the suddenly resurgent mood changes from moment to moment.

One positive is that your daughter did nurse her baby for nearly a year.  I recall that my ex - then a spouse - only promised to breastfeed for 6 months but continued for 14 months.  Human milk is such a wonderful food source for children that it's beneficial for as long as the mother can be convinced to continue.

Just a thought... Since it seems your daughter wants to go live her lifestyle again, maybe you could feed her daughter regular milk and other healthy juices when she decides to get antsy and decamp now and then?  Maybe I'm mistaken here but isn't some breastfeeding better than none?

It may be time to ponder what choices you have before you.  Apparently your daughter isn't receptive to the idea of long term therapy (DBT is highly recommended but requires commitment) so what can you do to focus on your granddaughter's welfare?  Has it reached the point where a court would agree you assume some level of protective custody?  Would others in your family support you or would they appease your daughter instead?
