When do you start buying things for baby? And what do you have so far.

I'm currently 26w4d and am anxious to buy everything for my babyboy but not sure if its too early? So far I have a swing, 3boxes of wipes, 2boxes of nb diapers, 2boxes of size 1 diapers, 4 packs of 32 nb diapers, and a pack of soothers. I also bought some onsies/sleepers and a tracksuit
I started buying things super early for my firstborn son who passed away at 20w so I don't want to get ahead of myself. Should I wait until after my babyshower in November to get more or should I just keep grabbing stuff as I go..
