Parents with two story homes- what were you glad to have doubles of?

First time mom here. We live in a town house, our bedroom/and nursery are on the second floor, and living room/dining room/kitchen on the first floor.

Trying to figure out what we’ll want doubles of so as not to need to lug stuff up and down the stairs constantly

So far we’re planning on having the bassinet with us upstairs and then a pack and play with bassinet downstairs.

We’re gonna formula feed so we’ve saved an old mini fridge to stay with us upstairs and are going to splurge on a baby Brezza bottle cleaner to hopefully reduce trips to the kitchen for bottle cleaning…

Neither floor is super spatious so trying to toe the line between doubling up too much and not enough!! Would love to hear advice from any other parents that had to deal with this!
