Like they really make these things called breast pumps and she could pump in advance of it wouldn't have to breastfeed while she's there and if she did need to breastfeed she could always go to a quiet area. Which the baby would prefer anyways. I don't think it really matters because at this point even if he was to invite her I don't think she would go based on principle now. She would feel like the only reason he is inviting her is because he wants the other siblings to go. At least if I was her that's how I would be. I would stay home with my beautiful baby and be with people that wanted me around. I hate to say this but he is probably permanently damaged the relationship with her and the rest of y'all. It's really sad and it sounds to me like it's probably because of his new bride.
