We got a few duplicates of items at our baby shower this weekend. What items are worth keeping 2 (or more) of, and what should we return?

Specifically, we got multiples of these items:

Take Along Tunes

Kick and Play Piano Gym (also got another play mat)

Sophie the Giraffe (got 3)

Also got duplicates of towels and a lot of books, but I figure we'll keep those for sure.
