My kids are majorly impacted by advertising geared for children and they saw a commercial for the singing toothbrushes: Tooth Tunes. My son picked out the "We Will Rock You" one in the color blue and my daughter has the pink one "Shake your Tail Feather" by the Cheatah Girls. I love these tooth brushes because I've never seen my kids so motivated to brush their teeth. The song starts up as soon as they start a brushing motion and the song lasts for 2 minutes which is the recommended brushing time, ideal for teaching kids how to brush their teeth independently. We've had their current toothbrushes for about 4 months now and the batteries are still going strong which I was worried about. If you are looking for a fun toothbrush for your child to help him/her be motivated to brush their teeth I recommend this purchase!
