Birth & up. Animals from around the world will twirl and grin down at your baby while the music will play for up to 20 minutes. Music includes classic lullabies from Beethoven, Bach, and Mozart, and a light show will dance on the ceiling above. As infants grow, the mobile piece can be removed and the light show can still appear on the ceiling while the music still plays along. Remote control included. Requires 4 D and 2 AAA batteries, sold separately.
