When will you buy baby items?

I’m not having a baby shower, but I’ve created a registry so that I can get a completion discount. I’m curious when everyone is planning to buy all of their baby items? I’m only 25 weeks and I think I have a good grasp on what I want/need, but I’m also afraid I might change my mind if I buy things too soon. Right now I still have energy for organizing, but I’m worried It’ll go away slowly as I get further along😬. I’m also high risk for preterm labor due to my low PAPP A. Do you think buying things around 30-32 weeks is too soon?
