I remember that not long ago, the Internet had a hot review of a grandfather “walking his grandson” photos, in these photos, an elderly man’s right hand holding a belt, the front end of the belt is attached to a one-year-old chest strap protection of the little boy, the boy enjoys playing, walking and even crawling, completely ignoring the surrounding people onlookers. Moreover, the grandfather (or perhaps the grandfather) holding the belt is also very calm, as if nothing happened to “walk” his grandson. Immediately there are enthusiasts of this phenomenon issued a sigh of emotion: “have seen the dog walking, have not seen ‘walking grandchildren'”. Interestingly, the network onlookers almost one-sided accusation of that “walking grandchildren” grandfather, both accusing him of disrespect for the child’s personality, but also accusing him of disregarding the child’s safety, in a variety of ways, to name a few. Obviously, in the eyes of these people, this old man is a “bad grandfather”, which is what they call a “bad grandfather”. What kind of grandpa could be a “good grandpa” in the eyes of these people? I understand that they may think that a grandpa who pushes his grandson in a stroller and walks among the flowers and holds an umbrella for his grandson to shield him from the sun is a good grandpa. I would call the practice of the “bad grandpa” with his grandchildren “walking his grandchildren”, and the practice of the “good grandpa” who pushes his grandchildren in a stroller for a walk “pushing his grandchildren”. “Look at the effects of these two behaviors on children. “It seems less civilized, less hygienic, and less safe for grandpas to leave their children on the road and let them walk and crawl freely. However, people overlook the benefits of this practice. In my opinion, there are at least three benefits of “walking” a little boy over a child placed in a baby carriage. First, movement is beneficial to the growth and development of infants and toddlers, especially walking and crawling for musculoskeletal development and motor skill development. In our clinical work, we have found that many Asperger’s syndrome patients do not have enough crawling exercise and good walking process in infancy and childhood, and they generally have deficiencies in motor skills, especially poor motor coordination. Second, life is a one-way street, and each stage of growth has a corresponding developmental task. During that time of crawling and learning to walk, it is the only stage of life where one observes the world and adapts to it at that height, posture and perspective, and it is virtually impossible to get back down and observe and adapt to the world at that posture and perspective again after one can walk. This is perhaps the reason why child psychiatrists advocate re-learning to crawl for children with sensory deficits. For example, infants and toddlers at that stage see that all adults are as tall as giants, that all adults walk very fast, and they even notice that some small insects crawl very fast. Such realizations and experiences are unlikely to reappear in later stages of development. Third, the “walked” grandson can safely and relatively freely explore the circular area with the length of the leash as the radius and the center of the circle where his grandfather is standing, and he can observe the expressions, movements, and speed of each stranger’s steps, and perhaps even the activities of certain insects within this area. Moreover, the relative abundance of visual and auditory stimuli in his surroundings will undoubtedly satisfy his curiosity and promote his interest in further exploration of the world. Of course, if grandpa can also lower his “stature” to bend down or squat down, hold his grandson’s hand, observe and touch the world with him, and communicate effectively, it may be even more beneficial to his grandson’s growth. Let’s look at the disadvantages of “pushing the grandson”. Although it may seem civilized, elegant and even poetic for a grandfather to stroll under the shade of trees and flowers with a baby stroller and a parasol for his baby and toddler, I think it is harmful and unhelpful. First of all, babies and toddlers placed in baby carriages are restricted by space and their movement is definitely inadequate. This will certainly have an adverse effect on the development of the motor and sensory functions of infants and young children. Secondly, the scope of observation of an infant placed in a stroller is very limited, which is no different from that of a frog sitting in a well and watching the sky, and this will affect the development of his observation ability and curiosity of the outside world. Inside the stroller, if the posture is relatively fixed, his visual observation range is limited to his front and above, even when there are novel sound stimulation around him, he will gradually give up the motivation of exploring the source of the sound due to the limitation of his own range of motion. Again, if infants and toddlers are used to being placed in strollers, not only may their motor and sensory development be limited due to space constraints, but they may also not be able to establish a habit of movement as early as possible, which may result in a lack of desire for movement since childhood and make them lazy, thus affecting their ability to adapt to the environment in an active state. As grandparents, would you like to “walk your grandchildren” or “push your grandchildren”? I think I would rather “walk my grandchildren”.
