Playbud uses toy-based play to track your young childs development. Based on child-development milestones, we have developed a scientific system of skills for your child to accomplish. The skills are toy and play-based, which child development science tells us is one of the most crucial avenues of healthy child growth. Playbud allows you to track these skills through simple evaluations. Currently, Playbud works with your 3 to 10 month old child.
