Receiving blanket, swaddle, burp cloth etc what is it

Ok. I know it’s a really dumb question. But I am a FTM and just a little confused. What is the difference between a receiving blanket and burp cloth? Do I need both?

I know what a swaddle is and plan on using swaddle me for night time, or anything similar to it. But do I need to use a different kind for the day?

And is there something special about muslin stuff? I keep seeing that everywhere

I’m sorry I know I sound so dumb right now. I just don’t want to over buy but also want to get the things that I need.
