What to get for our baby?

So we know the obvious but what are your can’t live without items!?!?

With my first it was trail and error and it’s been awhile so I would like some opinions!

We will keep the baby in our room at first and then move him to his crib!

Swing, wearable carrier, high chair, diaper bags?

What are your favorites, opinions on needs and don’t needs, and tips or information?
