I feel like I'm literally planning my own baby shower. My Mom and Sister In Law are supposed to be planning it. But she pretty much just does nothing tell like a week before and expects people to show up. So I picked the date and the invitations, and my Mom and I are doing the invitations, she is getting the cake and decorations, but we picked the theme, and I feel like I'm planning it all. It's frustrating because I have a feeling that she will back out last minute and we will have to get a cake and decorations.
