How quick do the 8-12 week puppy need to go?

So we haven’t got the puppy yet, I’m just trying to live out a lot of scenarios to prepare. I know every puppy is different but I want to hear how yours did.

How quickly did you have to take the puppy out after waking them up and take them out from the crate? Can they hold for like 10 minutes?

I’m thinking having his crate in our bedroom on the second floor, but I don’t want the poor thing to have accidents in my arms carrying him downstairs. And I also need to throw on some clothes and a jacket and shoes and he will have to get the harness on before we step out.

Or should I maybe have his crate downstairs and sleep next to it for the first weeks?

If you have the crate in the bedroom can you go to bed with the pup and having him not wake up when your partner goes to bed (ca 1,5 hour later) or do they wake and need to potty then as well?

I know you can’t prepare for everything, but I hate being unprepared so I try my best.
