Well, it depends. But there are a few reasons you should be serving alcohol at your baby shower:
1) It's fun for everyone involved. There's no reason to restrict yourself to boring non-alcoholic drinks when you could have a few glasses of wine and maybe even a cocktail or two. Plus, it helps to make the event feel more festive and exciting. Of course keep in mind who can and can’t drink—having said that, make sure to have some non-alcoholic beer and wine!
2) It gives people an excuse to loosen up and have a good time. Serving alcohol gives people permission to let go and be themselves without worrying about how others will perceive them for it.
3) Unfortunately it’s just expected. So even if you can’t necessarily drink, you’ll always have someone who just wouldn’t mind having a glass or two. No harm will be done if your guests have a sip or two, just make sure no one goes over the top with their alcohol intake!
