Our crib has the thickest rails so I couldn't find a darn mobile to fit. I got the Baby Einstein Sea Dreamer and although I had to jerry rig it to stay on the crib, she loves it! I am getting at least 10-20 minutes after she wakes up from a nap with her just smiling and cooing as she watches it. It has made pumping a lot easier.
