Since winter, the number of children with muffling syndrome has gradually increased, so what is “muffling syndrome”? To put it bluntly, it is to wear too much, cover too thick to cause the child to sweat, deflate, and even dehydration, shock. The critical condition is even too late to rescue, if rescued in time some children may also have sequelae, or even lifelong disability. In the past, there were many children, there is no way and no financial ability to take good care of each child, so sick just dragged, not to go to the hospital as a last resort, now, there are fewer children at home, many are only children, economic conditions have become significantly better, everyone’s concept has changed, the child is also doubly concerned, always afraid that the child is hungry, freezing, think that the fatter the healthier, every day to the child wear thick clothes, but also to wrap the quilt. I do not know, the child would rather starve a little, freeze a little, resistance to be stimulated, physical fitness to enhance. Especially now into the winter, children’s clothes more and more through thick, especially babies, wrapped tightly, someone often look at during the day, feeding ah, changing diapers, but at night is likely to happen smothering syndrome, so parents are cautioned not to over-wrap the child to avoid accidents.
