what could be really fun is the bat members reactions to finding out that their best friend has knocked up their batsis XD i.e Bruce-Clark, Dick-Wally, Jason-Roy, Tim-Kon, Damian-Jon that sort of thing
This assumes that the Reader is the same age as the Batfam and lover mentioned.
Bruce Wayne:
Of course, he knows that you and Clark are together. Clark had talked to Bruce before he asked you out, partly to avoid a scene and partly because he figured Bruce already knew. Bruce doesn’t know any details about your sex life and aims to keep it that way. That doesn’t stop him from scowling when you both come to him, more than a little sheepish.
He struggles between wanting to scold you both and terror at being an uncle. The two of you are adults damn it! You should know better than this! After the lecture of a lifetime, he’s more open to the idea, mostly because you’re so happy he can’t take that joy away from you.
If you thought Bruce was protective before, think again. You having a baby drives him into overdrive and even Clark is stunned by how much he’s running himself ragged. Your brother spares no expense helping you get ready and you’ll have to put your foot down to get him to stop. Clark might have to deal with a couple of extra dirty looks here and there but all in all it goes over relatively smoothly.
Dick Grayson:
Dick struggles with you and Wally. He loves you both so much but he doesn’t love how mushy Wally can be with you. There’s no irony lost to you, Dick complaining about Wally being too physically affectionate in public but you keep your mouth shut. Overall, Dick is happy for the two of you being together but he’s shocked when you tell him about the baby.
You both get a lecture that could rival Bruce’s. Wally tries to help by providing more details about how the two of you ‘have been safe’ but that sparks a ‘thanks I really want to know that about my sister’. In the end neither of you can win and you just have to let Dick get it out of his system.
He’s the one to ask outright if the two of you are going to stay together or not. Breaking up isn’t something you and Wally had talked about but Dick’s question does cause some awkward tension. It’s a good conversation to have and you both agree to stay together but Dick is the one who starts it. He’s over the moon at that point and is happy about the baby. He had been nervous about picking between you and Wally and now? Now he can go into doting uncle mode.
Jason Todd:
Jason had been nervous when Roy asked you out. He loves Roy but he knows that the two of you are going to get into trouble all the time. You’re both fun loving and he knows it’s going to lead to some wild adventures. He didn’t expect that adventure to be parenthood.
Did he handle it well? No and he’s man enough to admit it. There was some yelling and slamming into walls, especially when Jason mentions Liam. He knows that your relationship is much more stable that Roy’s relationship with Cheshire but it still has him being nervous. The two of them work it out quickly but it’s a tense couple of hours. Jason is able to handle it well considering what’s going on and you appreciate that no one is hurt.
Jason knows that Roy is a great dad and will be there for your kid no matter what. It makes him feel good to see you interact with Liam and how much the little girl adores you. It gives him hope that the two of you will work out for the long haul. He doesn’t know how to react when you tell him that you want him to be the godparent; he did not cry damn it!
Tim Drake:
Tim can’t say he’s surprised if he’s being honest with himself. He knew that Kon and you had been dating for over six months now, he was waiting for you to come clean about it. It’s hard being a great detective and having to lie to keep his friends happy. He’s not at all happy that the only reason you tell him is because you’re pregnant.
He gets insecure about it, not that he’ll say it out loud. The two of you have always been close and it’s not like he doesn’t approve of Kon. Tim loves the guy. He questions if the two of you had been close or if it was all in his head. There’s some avoiding that Kon eventually has to intervene in, sitting all three of you down to talk. It clears the air, even if there are some tears.
He’s really supportive of the two of you being parents, even if Kon is freaking out. He does his best to support his best friend, going to classes with him and learning how to be good parent. Tim becomes an excellent baby sitter and offers to babysit all of the time. He’s a godsend.
