When did you start buying baby things

Abbie • Pregnant with baby #1 so excited!!!
Hi everyone!
​Just wondering when everyone first started to buy things for their baby? Or when people plan to start buying? I'm just so excited and want to start buying everything now, but don't even know what I'm having yet. ?? I know some people start buying the second they find out but I don't know what to do. It's so tempting ????
