Query: long life

My son is 2.5 and he still LOVES this toy and turns it on every night. The music is so fun, yet mellow, and the lights and motion are so ammusing. The best thing from a Mamas percpective is that the batteries last FOREVER. even with all the music (which lasts a really long time) lights, and motion. far superior to any of the other crib toys we have owned.
