Well d'uh....of course you buy baby clothes!
What I want to stress is to focus buying baby clothes that aren't size 0-3 months. And even skimp on the 3-6 months ones too. Why? Because people like to buy itty bitty tiny baby clothes, socks, and shoes. People also love to gift you baby blankets, so don't go over board like we did.
It's also hard to believe when you're pregnant, but those first few months go by so fast and they grow so fast, well, before you know it, they are in the next size. Of course it's a rare bird (hint, hint friends & family of pregnant woman!) who buys an outfit for the lil one that is larger than six months.
So...if your budget is tight, focus on the larger sized items. Heck, you can always run out and grab a new pack of onesies.
