Baby shower. Who to invite?

My baby shower is coming up and invites are being sent out. Earlier this year one of my co workers had a baby shower and invited all of the women in our department at work. I feel pressured because she included everyone. We have 11 women in our department, including myself, and I am not sure if I should invite all of them to my shower. I don't want to come across as begging for gifts, but I also don't want to seem like I'm not including people if I invite only some of them. My co worker's shower was only a 5 minute drive from where we work, but mine will be about an hour away because my mom is throwing it at her house. Only 4 of us, out of the 11, showed up to my co workers shower and I'm sure I'd have less (if any) show up to mine since it's going to be a far drive. I really like my co workers, I'm not super close to all of them, but they have been amazing to me and I look forward to seeing them! Would it seem like I'm begging for gifts if I invited all of them? I think regardless of if I invite everyone or not, they will still get me a gift. I didn't invite any of them to my wedding shower/wedding (I had only worked in the department for 3 months when I got married) and they still all went in together and got me and my husband a big gift. I'm just so torn on what to do because of the distance and seeming like I expect things from them. 😩
