Query: Best mobile ever

We bought this mobile because our daughter, who was six weeks old, would always wake up as soon as we got her into her crib. if we didn't pick her up and rock her to sleep again she'd just start to cry and wake herself up all the way. with this mobile we can set her in her crib and turn it on and she watches the lights on her ceiling and the fish and is lulled back to sleep. that means we get some sleep!
