Idk if this is the one you tried but we love it!
Boppy or nursing pillow. I use my Boppy SO MUCH. Also an extra cover.
Portable white noise machine. I love mine and use it way more than I thought I would. Clip it to bassinet, take it in stroller, in car, etc. https://www.target.com/p/yogasleep-hushh-for-baby-portable-sound-machine/-/A-51030371
Royal Angels nail file!!!! If you know you know! So much easier (less scary) than clippers: https://www.amazon.com/dp/B077QBJNVM/ref=cm_sw_r_cp_api_glt_fabc_6CPFM6EPGJ355M282323?_encoding=UTF8&psc=1
Baby wipes! You go through baby wipes like crazy. Add them to your registry. Personally I didn’t put diapers since didn’t know which kind we were going to use. Some people add a “diaper fund” to their registry though.
Two way zipper PJ’s! Everyone told me this, but it’s so true for night changes, or any time changes. Cotton are great (I like Target, Carter’s, old navy), but can also get more expensive bamboo ones for the softest silkiest baby hugs. I bought more Carter’s and Target ones after baby was born.
Vava night light. A mom friend recommended this after I had my baby and even though I already had been gifted the Hatch (which I love) she sold me on it. It’s AWESOME. I carry it around at night when I need to change or feed. You tap it to change level of light.
Black and white cards or books. Baby loves them for tummy time or literally any time. There’s a book called “Black and White” that is just images and has given my baby hours and hours of entertainment in her first months.
Some other random items: - crib mattress cover / sheets or pack n play sheets. I forgot about these. - a wet/dry bag for holding dirty clothes while out - bottles (Babylist has a bottle sample pack so you can try a variety of popular brands to see what your baby will use.) - Baby wash cloths: https://www.target.com/p/baby-12pk-washcloth-set-cloud-island-8482-white/-/A-79396939
I also recommend using Babylist. It was easy to add from Target, Amazon, and anywhere else in one place. If you added an item from Amazon it often gave the prices for other places which are sometimes cheaper for baby things.
