Ages 12 months and up. Put toddlers in control with the Curious Learner Remote. This remote can engage toddlers at a wide range of developmental levels. It is a great auditory sensory toy for any toddler because every button makes a sound, but it also repeats each number that toddlers press and has a quiz function that challenges toddlers to find numbers and shapes on the remote. Each remote requires 2 AAA batteries, included.
