Ladies tell me if I'm wrong or overreacting please. I'm having my baby shower this Saturday which I'm super excited about and so happy I get to have one. But My grandma insisted on inviting my uncle and aunt who have 5 kids to come to the shower.

Normally I wouldn't care but were having the baby shower at an Italian restaurant and paying per person for everyone to eat. And the only time anyone really see's them is when they come to parties.

And the things is they don't ever being bring gifts... I'm not being selfish because i love my family and i want everyone to be there to celebrate the baby but dang atleast bring something Idk. And I know they aren't bringing a gift beacuse my grandma said so.. Them bringing a gift isn't what's making me upset it's the fact that were paying for 7 people to eat for nothing and were not exactly rich either. Am I wrong for thinking this?
