What is a good gender-neutral baby shower gift?

Assuming no access to the baby registry (or perhaps all the good stuff has been taken!), I enjoyed receiving a foldable outdoor/water resistant blanket. It encouraged us to be outside!

I discovered Zutano booties with my third a couple of years ago, and I love them so much they are now my go-to baby shower gift. They also come in plenty of neutral colors for boys and girls.

In addition to something from the registry (which is always my preference!), I'd suggest giving a couple of your favorite children's books.
