When to start buying baby stuff?

Kourtney • Baby #1 Born 6/8/18 💕

We’re finding out the gender this week (from my genetic (blood) test). People have already started buying us onesies and such. When did you start buying things like furniture for the nursery and car seats and such? I’m 14 1/2 weeks. Which seems kind of early to me but at the same time my parents keep asking what we want for Christmas and that kind of stuff is all I really want that way we can save that money for the baby and for hospital bills. Is 14 1/2 weeks too early to start nursery shopping and car seat shopping?
