A toy is an object or device designed for children to play with. It is typically designed to entertain and stimulate learning and creativity. Toys can come in many different forms, ranging from dolls, cars, puzzles, building blocks, games and more. Some toys are also collectible items for adults.

Toys greatly aid a child's development. They enhance cognitive skills like problem-solving, boost physical development through active play and support emotional growth. They also foster social skills, stimulate creativity and aid language and sensory development.

Toys are suitable for a wide range of ages, from newborns to adults. Each toy usually comes with an age recommendation on its packaging, to ensure it is developmentally appropriate and safe. For newborns to 6 months, soft toys and sensory items are appropriate. As children grow, toys become more complex, like building blocks for toddlers (1-3 years), simple board games for preschoolers (4-5 years) and more challenging games and activities for school-aged children (6-12 years). Teenagers and adults may enjoy puzzles, brain teasers and hobby-related toys.
