Hi Mom/Grandma,
I think your post will resonate with many grandparents on this site--the sudden and seemingly inexplicable switch from loving to hating, isolating you from grandkids, the unreasonable demands about what you're allowed to talk about, twisting the narrative to make you sound like a monster, accusing you of things that never even happened. The saddest part is that a defenseless child is used as a pawn. You're worried not only about your daughter, but how her emotional and often angry outbursts can affect your grandchild's well-being.
I suspect that the estrangement is only temporary. But I also suspect that the push/pull and alternating periods of estrangement will continue for as long as your daughter isn't getting therapy. The way I see things, any outbursts from her are a sure sign that she's under a lot of stress, and she's taking it out on you. Being a new mom is certainly stressful.
On these boards I've seen several posts about a BPD mom finding issue with accepting baby gifts from family members. This might be a form of jealousy--she feels "shortchanged" in some way, or "upstaged." She might not like to be reminded of you, because she knows she's acting badly, and she feels a mix of shame and guilt. The idea that she'd have to thank you or "owe" you for the gift is repellent, and so she'd rather not receive any gifts. Deep down she might feel jealous that her family members give gifts to her baby but not to her. Or maybe it's a simple as wanting to hurt you, to punish you for purported wrongs, and refusing gifts is a powerful way to do that, because she knows you'll be hurt. That's my take. My advice would be not to make any fuss about refusing a gift--you can just put the gift aside and wait, return it or gift it to someone else. That's what I do.
Sometimes on these boards, a formula that might have a chance of working is to make any visitation with the grandchild about your daughter's needs. You could frame a visit as giving your daughter a needed break, some time to herself, some time for self-care. But if you make a visit about you (I haven't seen my grandchild in months!), then your emotional needs come to the fore, as if your feelings are more important than your daughter's. You could also inadvertently be signaling to your daughter that withholding access to your grandchild gives her power over you, and I think she's likely to continue, to try to punish you and control you. Does that make sense?
In the meantime, I know you're hurting. For now, I'd advise to sit tight and wait until your daughter reaches out. My guess is that she will soon enough. If she doesn't, maybe you could reach out with short, non-emotionally-charged message like, Thinking of you, hope you are well, to open the door a crack. But I'd advise against anything that mentions your needs/emotions or puts any obligations on your daughter (I need to see my grandchild, when can I come visit?), because I think it would backfire. She has all she can handle with BPD and a baby--she can't handle the stress of your emotional needs or feeling that she's letting you down in any way. She should come to you when she's ready.
