I found making a baby registry extremely overwhelming. This is very much a list registry of baby essentials without the fluff. This is a list of things I have really found helpful & why. I have tried to give a little background info as well to help you make the best decision for you!
I always tell friends to add diapers of all sizes to their registry. It is so helpful to have all sizes on hand so you can just transition up. I was also fortunate to be able to get a breast pump, replacement parts, & milk freezer bags through insurance (linked below).
