So my cousin (the one who found out she's having a baby in a month) has her registries up, but they're REALLY bare. Like, I'm not even sure there's enough stuff for everyone of her friends and family to have something to buy. Obviously, she may add to them, but given that she only has till next weekend to do so, maybe not. And of course, she's probably getting a lot of gear as loans. But this is someone who didn't want kids and doesn't know much at all about what you need for a baby.

So can you recommend something that was a really great item you used a lot, that might not be something a first time mom with no clue would even think of?
