Coping with estrangement from my mom while becoming a mom.

I’m in the beginning of the second trimester and think I’m finally fully NC after years of a strained relationship with my mother. She has gone down the alt-right pipeline said she wouldn’t be getting vaccines when the baby is here. For context, she lives across the country and would be flying out to where I live. The politics and vaccine stuff was really the final straw to years of what I consider toxic mother behavior on her end. I get along with my dad, but he’s still with her and I don’t expect him to try and be around if my mom won’t be (largely bc he doesn’t want to deal with the negative fallout from her).

However, I’m feeling really guilty about my child likely not having a relationship with all of his grandparents or having other family members who will be able to babysit (my partner’s parents are old / not really capable of helping). I should be excited right now but tbh I’m depressed/anxious. The lack of potential help is especially jarring due to my job not being compatible with motherhood/daycare hours and my partner not having the type of income we can all rely on.

Have any other estranged adult children been here? what advice do you have?
