They are super cute so you don't have to mess with shoes if you're going out, and they stay on.
Someone gave us a ton of headbands with bows in all colors. I still use them all the time. I think they got them on etsy.
So many people have sent me the picture of the copy/paste onsies, but no one has bought them for us and I think they're adorable!! I did get a set that say "I was planned" / "I was not"
If you're close to the dad, I got my H a shirt that says "I laugh at your one baby " he loves it. I got it on cafepress.
Don't get cute tiny outfits. My girls only wore sleepers for the first few months. All the precious newborn outfits people gave us were a waste.
My sister got this thing from my aunt where she got to pick out specific meals from a delivery service. it was awesome. And what I needed but did not get was all the boring practical stuff one needs for a baby like burp cloths, nipple cream and the like.
