Baby Shower Stress

I'm becoming very stressed about my baby shower because of the amount of people who want to help. I am combining both my family and my boyfriends family to have a big one.

My boyfriends mom is dead set on throwing it herself, but this is my family's first grandchild and they're also excited to throw one for me. I have offered to have them both just work together on this whole thing by my mom thinks it would be easier to have two separate showers. However my boyfriends mom is offended by that idea. I just want this to all be drama free but don't know what to do 😥
