Pop in three and pop out two – there are a zillion combinations that you can do with the Ballyhoo set of balls from B. toys! Little ones can play with all 6 balls by inserting each baby ball into the big ball, then rolling it around to see what happens! Or they can take the little balls out and explore all of the different textures, colors, and patterns. These multi-sensory toys will engage a baby’s senses of sight, touch, and hearing with bright colors, different textures, and squeaky sounds. And it could develop their social skills if they roll or bounce with a friend or a sibling! Not to mention, playing with these balls can also improve fine motor skills, hand-eye coordination, and dexterity. Recommended for babies 6 months and over.
