After giving birth what to expect or prepare if I don't have anyone around

So I was wondering, let say I don't have anyone around after I gave birth be it C Sec or natural and I'll have to give shower to my newborn since day one.. do you have any advice on what kind of bathtub I should have or Diaper changing platform high enough so that I wouldn't have to squat? I believe I'll be in pain still.. or how do I do this? #pleasehelp #firstbaby #advicepls
