FTM and overwhelmed by the amount of products they say newborns need..

What are some things that you don’t REALLY need. For example wipe warmer/bottle warmer/air purifier (there’s more but thats just examples)

A lot of these items are on baby registry checklist but I’m just not sure if I should spend the money on items like this. I feel like most moms over buy and then don’t use half the stuff they bought. I don’t have extra money to just throw around. If baby needs it I’ll buy it of course but I just need to know the necessities. Before splurging in extras.

Thanks!
