One thing I was advised was not to revolve everything around the baby while being pregnant (not meant in a nasty way at all and still taking care of yourself) but just do stuff you both love doing together and alone while you still can. Like Lucyann said whether it be a meal out together or just snuggling. I was scared when I first become pregnant that me and OH would only be able to talk about the baby and baby things and baby activities etc lol obviously she is our world and we love her to bits but its important you remember each other as well and I've really grown so much closer to OH, obviously we have long talks about the baby but we also have other things to do and talk about as well. Hope that makes sense
