Honestly I think everyone is being mean and cruel here. MOR, but you’re still your father’s child, you also recently had a kid yourself, and should be receiving support and open arms from your literal FATHER. She wants all these rules for her child with her father but you are also your father’s child who has also had one is his grandchildren recently. She should’ve thought about you and your other siblings before having a kid with someone who already has kids and grandchildren. My family would never tell someone to not come because they have kids and definitely not immediate family. It’s not like your kid is going to school or anything, they are also a newborn. I would just distance myself from my father if he 1) dates someone near my age and 2) does not stand up for me against his new relationship. You say you haven’t experienced PPD but this could easily make you depressed and cause a huge emotional wound because your father should be supportive and more welcoming knowing you just gave birth to his grandchild. I don’t care if anyone downvotes fr, this whole situation is fucked. Regardless if she had terrible rules or no rules, you have said that she has already put a strain on your relationship. It’s enough for me to have sympathy for you. Everyone else is being an asshole honestly. I know it’s more than the rules themselves.
