Hey,

I was wondering if anyone has a snippet for the bot going placing a bed/finding next bed, go to it and then sleep, once it is night?

wdym snippet?
And I think you would need to make a mod(with the baritone api) to do such things, becouse baritone doesn't have a scripting system(at least that I know).

Baritone doesn't have scripting. However the client that you could be using might, however, anyway, this is the wrong place to add if that is the case.
