Basically, this is a great travel toy that can easily fit inside your purse or diaper bag, and pulled out when needed. Babies delight in the colors and teethe on the sturdy plastic sides. Older children learn about colors, numbers, size, volume and building. It’s a great toy for the bath too; so when visiting grandma, you’ll have a toy that entertains for a great while. Many moms love this toy because young babies at 6 months learning to grasp, will reach for them, chew them, put things inside and out and typically bang them together. As they age, they discover new purposes. At age 3, a child may recognize the numbers and certainly see the number of holes and delight as the water or sand runs through them.
