As long as the child plays quietly in the walker and walks on his own, he can let him stay for half an hour. However, if you don't care about him when you put it in, it will be very harmful to the baby if you let your child play there all day. First of all, the walker holds the baby in it, so that the infant loses the opportunity to learn various movements. If the baby is in school climbing, he will not be able to get a crawl. If the baby is in the station or walks, he cannot stand alone. He may walk later in the future. This is not conducive to promoting the overall development of the body. Second, the infant lacks the ability to connect with the various things around him. He will only leap to the left for a while, and rush right to the right. No one will approach him, making him a shocking, radical child. Parents are busy. In her own affairs, she does not speak with her children, nor does she hold the child's hand to practice walking. The baby's learning feelings, thinking, and language development are limited. Third, accidents occur when babies are unable to care for themselves because of their parents. Because no one is near the baby, the baby rushes around in the walker, may touch the edge of the door, stones, and carpet to make the car overturned, or the wall or the corner of the table hits the child's hand, causing the baby to be injured.
