Idk what to do about my dad

Sk

For some back story, my dad and I have always been pretty close, but he has boundary issues. It’s known in our family that if you want something a secret, he’s not the person to tell because he will tell everyone. I currently live with my mom to save money, and am pregnant with my first baby. My dad doesn’t seem to get that every little thing involving the pregnancy and the baby isn’t his information to give out. The baby’s father is not a great person and has chosen to not be involved, and my dad seems to think he can broadcast that information to everyone he’s ever met. I’ve asked him time and time again that if he gets asked anything about the baby’s father or pregnancy in general, to just tell the person to ask me. If they aren’t comfortable asking me, then they don’t know me well enough for it to be even remotely their business anyways. He will argue with me about it though, he doesn’t get why I don’t want him telling everyone, so he goes and tells people anyways. He also won’t listen to my wishes for who knows when I go into labor. I don’t want people showing up at the hospital, so I don’t want people knowing until I’m about to leave the hospital that the baby has been born. He takes personal offense to that though and says that’s a ridiculous request. He doesn’t get that it’s also a safety issue that I don’t want word to get out to the baby’s father and have him show up. I was explaining to my dad that i won’t be allowing people to kiss the baby for a while and that no loose blankets or anything will be allowed in the crib/bassinet, but all he did was argue with me on it. I’m 18, so my dad isn’t used to treating me like an adult and doesn’t get that this isn’t something he has a say in. Right now I have his number blocked to get some space from him, but I know I can’t keep him blocked forever. I’m prepared to not let him know when I’m in labor and not let him babysit until the baby is much older if need be, but it feels cruel to do that to him. He just doesn’t understand where I’m coming from no matter how many times I explain things to him or what way I explain them. I don’t even know what to do anymore.
