First of all, hand me downs!! Nothing so useful as hand me downs. I had a lot of stuff from my aunts. Some of it about 25 years old, but it looks and feels newer than most new things. (How is that?!)
I also had a long excel list with 95 or 100 items, which frankly, was quite useless.
However, this link is a good guide for what you need. Of course, there will be a few things that you will want to add, but I don't think we needed anything else for the first two months. Besides gripe water (which is more for the parents than the baby anyway).
