My mom just passed away and I need help preparing baby registry

I have only spent time preparing for labor and have barely spent time on any registry. I am really having a difficult time gathering my thoughts about the stroller, car seat combinations, and the bassinet/where baby should sleep during the day?

I am trying to get the essentials where the baby sleeps and lays to be greenguard gold certified and as nontoxic as possible.
I’m worried about buying things that I don’t need as we have a small home and live minimally. With her loss, it’s just been really hard to concentrate on getting this registry together. I have only had time to work and just trying to keep myself healthy and read about preparing for labor and how to actually care for the newborn when they come.

And if anybody has any suggestions on videos to follow on how to take care of a newborn, I would sincerely appreciate it.
