While baby showers happen all year round, it seems like this time of year, they happen more. I always like to buy books for gifts (Librarian) and I know it's popular for the hostess to ask everyone to bring a book to start off the child's library.
And you get multiple copies of Goodnight Moon, The Very Hungry Caterpillar, or Moo Baa La La La - all of which are fine books, but you don't need four copies of each.
Here's what I like to gift:
First mostly board books, for endurance.
Second, I LOVE the touch and feel books and there are So Many to chose from. There's lots of pieces to touch and interact with the child.
Third: I Love concept books, it's never to early to learn, especially those from National Geographic. They have bright colors and great photographs.
Fourth, I Love these classic stories told as board books. They're not a retelling of the story, just using bits from the story as an introduction.
Hope this helps!
