Are these things Necessary?

hii first time mama & im adding stuff to my baby registry & starting to get things & was wondering if these things were necessary or just kinda useless & didn’t use them at all, I’ve heard mixed emotions about it>>>>

Diaper genie or off brand version in general

Baby bullet with steamer

A whip warmer

A changing table

A bottle warmer

Boppy pillow

Thank youuu. Also what’s everyone’s must haves that I can add to my registry. Pls & thank you!
