I loved this crib soother. On those nights when my infant didn't want to fall asleep after nursing, I would put her in the crib and turn the soother on. It kept her entertained for 20 minutes, which is more than I can say for similar products. The batteries lasted for over 3 months as well!! It is also nice because it has a remote, so you don't have to let your child see you if you decide they need another 20 minutes.
