Baby shower for 2nd or 3rd children

My cousin is inviting the entire world to a baby shower for her second child, her second boy. I’ve always felt like a baby shower is to help momma get set up and after the first there shouldn’t be much you “need” yet she’s registered for all new baby gear, travel system, bouncers, crib, swings, all the expensive stuff I know she was given at her first shower. I get celebrating the baby and doing a sprinkle or something if your baby is the opposite sex or if it’s been years since you had a baby, but I feel like if your kids are less than 2 years apart and the same sex you really don’t need a full blown baby shower with all the gifts. Am I an asshole?
