Purchased in 2022. I think it can be used for a long time, from when the baby is small to when they are a toddler. You can learn various things such as colors, shapes, alphabets, and numbers in a fun way. Also, when you press the buttons, sounds and lights come out, which helps develop fine motor skills. A colorful educational toy that allows you to recognize shapes and learn numbers. One blue block is missing. Please purchase if you understand this.
