I received a Baby Einstein Sea dreams soother (http://www.toysrus.com/product/index.jsp?productId=12482416) as a gift and its an item I never had on my radar.
I've considered returning it because I never imagined using one, but now that I have one gifted to me, I'm wondering if its worth keeping.
Do any of you use crib soothers? Do you like/dislike them and are they necessary?
