This is a great training phase for him. The main function is to protect the baby's pillow and reduce scratches when the baby falls while crawling or walking on a hard floor. The embroidered pattern is very beautiful. This is a big hole net, somewhat like a small pumpkin. The protective pad is designed in a circular shape, gently embracing the baby's knee. Even if it's only a size 1, it won't work if the baby is at a toddler's age. If he is too young, the cushion may tilt slightly and not be fixed when he climbs, but if he does this, he will be safer and he will grow up quickly, and it will be faster.
