Is it inappropriate to have wine at a baby shower?

I'm 18 & I've never even drank wine. I don't plan on doing it while I'm pregnant either so don't lecture me. I don't have friends so only family will be there, mostly women 30-40 & I want them to enjoy themselves. Not getting drunk of course but just relaxing & a lot of girl talk about experiencing life with a child since this is my first. Do you think that's a bit too much? I've been overthinking this shower but I really want my guest to enjoy it & know that I appreciate them. There won't be any children there. I'll be the youngest person in the room.
