[0002] When the weather is clear and the air is fresh, most parents will choose to take their children out to play. On the one hand, letting children see more sunlight helps their absorption of calcium and makes them grow healthier. On the other hand, letting children go for a walk can also allow them to come into contact with others, so that they can become more sunny and cheerful. Most parents use strollers to take their children out to play when their children cannot walk alone. The child sits in the stroller and the parent pushes the child. While the child grows up healthily, the parent also exercises their body. Therefore, strollers are loved by many parents.
