Registry must haves?!

St

What are some necessities and must haves to put on a first time mom’s baby registry?? Maybe some things some of you wished you would’ve added or something you never thought of but got anyways. I’m having a baby boy in November and I’m a little clueless. We already have the crib, car seats, stroller, Bobby pillow and lounger, a few pacifiers, blankets, and several clothing items. Thank you!
