crib toy/soother ideas

HBear19

I've been having trouble transitioning DD into her crib. She does great falling asleep for naps in her swing by looking at the mobile above her head. I'd like to get something for her crib.

 I've heard lots of moms use the FP seahorse, and I also saw the planet mobile in the store, or the ocean wonders take along projector (with the big yellow star).

 What has worked for you and your LO? I can't decide which to buy!
