Jin: He would probably have to leave the room and think. "I'm going to be a dad.." But when he came back in he wouldn't let you go, spoiling you until your baby was born
Yoongi: He wouldn't react for a bit, and then he would break into smiles and hug you tightly. "I can't wait for our baby Y/N.."
Hoseok: Hoseok would probably burst into tears and fall over. He wouldn't speak as he held you in his arms and cried into your shoulder. "I'm so excited.."
Namjoon: Joonie wouldn't be happy at first, as the god of destruction, he wouldn't believe he could raise a child. Then finally hugging you, "As long as your here.. I'm here."
Jimin: Jimin would be excited. He would pull you into his arms and kiss you. There would still be worry behind it all but he would be strong for you.
Taehyung: Tae would sob, picking you up and spinning you around while whispering I Love You's. We all know how much this man loves kids, so he would probably be the most excited.
Jungkook: Kookie wouldn't know what to do. He's just a baby himself. He would lay beside you and rub your back, kissing your cheek, not saying a word.
