Is it wrong to ask people to bring food to your party? Please read first.

So I'm having a baby soon I'm 35 weeks and I don't want people coming to see me at the hospital and in also breast feeding. This is my second child with my first people dropped in to see my first so often that I got stressed out and couldn't breast feed him properly. So with my second child I'd like to try again without the stress of people popping in unannounced. So instead I'm having a party on labor day weekend to give me a chance to establish breast feeding. Now my question is. There will be lots of people coming I can provide some of the stuff but not all of it. Would it be wrong to ask people to bring some things? If so how should I do it? Should I ask them to bring some meat? Plates? Cups? Side dishes? Drinks?
