I'm not pregnant but my friend is

Hi. I'm not pregnant but I have a friend is and she's invited me to her baby shower. I'll take pictures of what I got. What kind of diapers do you by for a baby that hasn't been born yet? She's going to need as many diapers and wipes as possible so I figured maybe I'd buy her a few different things. Is that a good thing to do or do I buy as little as possible? Any information really helps (: even let me know what you would want as a mother who is expecting soon. Thank you. And I hope It doesn't offend anyone me posting in here. This is what I've bought so far. I got a gift recipe is she doesn't want them
