Product recommendations!!

So, I need some product recommendations.. I’m a FTM & I have no idea what to get for my boy!

I’m 21 weeks so, mind as well start soon I don’t plan on having a baby shower until my baby is born. I wanted to get the things baby needs on my own. So far, I got a

Playpen (easier to move around than a crib)

Swing

Stroller & Carseat

What else would baby need? What bottles do you recommend to avoid colic? Formula pro is it good?
