Baby shower advice 😞

So I’m due July 2 baby shower would be Jun 19. First baby for me and my husband first grandchild on his side of the family. I wasn’t planning on a baby shower but my mother in law insisted in doing one again his side of the family since mine in 4hours away and I’m really not close to them . They started the planning between my in law and brothers in law everyone is paying for something including our selfs. (No issue there) … They love to drink My husband not so much but everyone else for sure .. I spoken to my brothers in law and told them they can invite their friends nothing crazy .. Today one of them said something about making sure we have lights in the back KEEP IN MIND THE INVITATION SAYS 4pm to 6:30pm . He was letting us know how he invited a lot of people and wasn’t trying to end the party at 9pm … My response was .. what are U trying to have a club party ?? I thought we was celebrating My Dauther life ? (His response) no I’m just not trying to kick anyone out early or anything like that no one is going to be here on time plus we plan kn getting FK up .. I’m already on edge and overwhelmed because my father in law drinks every weekend as my mother in law even a 6 pack starting Thursday, then Friday Saturday and Sunday they just drink drink .. (father in law) Get fucking weird/ stupid .. argument they have found him on the back yard not being able to get up since he so drunk .. Ones he sees the beers and drink he is going to want to start getting drunk right away … 😓😥😑 I Don’t want to be embarrassed or have drama but I can’t help to start to regret this baby shower coming up . Any advice?
