19 weeks

I am 19 weeks 2 days. I was wondering when do you mommies start buying things for your babies? I wanted to buy the crib and other things like just start buying things. I had my first at 26 weeks and didn’t have anything yet and I don’t know if this one will be born early too. So clothes I don’t want to buy yet just in case I have to buy premeature clothes but I wanted to know do y’all think it’s too early to buy the crib and other things like a swing and things like that?
