How to increase romance and intimacy in a complicated relationship? (Long Story!)?

[Ryguy]

So about a year ago i started talking to this girl i work with and we really hit it off and we almost instantly became attracted to each other and are now dating. However a few months after we started hanging out she found out she was pregnant from her ex-boyfriend who is now completly out of the picture. I still am very interested in her and I love both her and her baby. So before we were oficially dating we would hang out really late at her house and we would kiss and stuff on the couch and she seemed really into me and i was really into her and I loved being able to do that with her. However the babys sleeping pattern has changed alot and we arent able to hang out late anymore and now it seems like she doesnt make an effort to have any romantic or intimate moments with me. It may be because we hang out during the day alot that there just really isnt an opportunity for us to have any intimacy. So im just asking is there a way I can bring this topic up to her without making it seem like thats all I care about or without sounding stupid. Im not looking for sex or anything like that but i just feel like that aspect of our relationship is missing. Am i overreacting or is there a way I could solve my problem or at least be able to talk to her about it. Thanks for taking the time to read my problem and i really need all the advice i can get. Thanks!!!
Ok so i realized after reading the first answer that I want to clarify that I do really love this girl and her child and that even if there was no intimacy between us I would still love her and want to spend time with her. I was just wondering if there was a good way to bring this topic up and if not please tell me cause maybe I am being too selfish.
