We bought this when our second child's birth in 2009, he STILL LOVES IT! He would wake up in the middle of the night, turn it on and go back to sleep by the time he was a year. Same thing with our 3rd baby and now we are pregnant with number 4. Completely worth the price and the music is beautiful, soothing and much less irritating than most baby mobiles, swings etc. We like to switch it up and use the nature sounds or heartbeat when they are newborn to help add, \"white noise\" which is a much needed survival tool...especially for colicky babies, (which 2\/4 so far have been# Speaking of that, must also suggest the Happiest Baby on the Block DVD! =) LOVE it and tell everyone about these 2 things...#ok, adding in a tower fan pointed towards the wall for the white noise as lifesaver too!) Amazing! Once baby is addicted to it, MUST have extra set of batteries on hand at all times. Really not a battery hog, do last surprisingly long. We are still dependent on it and have guaranteed sleep for all...Unless it's 3am and batteries die. Seriously. Have even taken to Hotel with us to make sure kids can sleep in strange place when traveling.
