I have seen an 8-year-old child with clumsy hands and feet. He can\’t even tie his shoelaces well. His homework is crooked. He can even write the answer on the test paper in the blank space for the next question, but the result is always bad. OK The parents were worried about this, and finally took their children to see it after being reminded by others. Turns out it was another sensory integration disorder. The child was later found to have been delivered by caesarean section. Pediatric experts told reporters, “Currently the medical community believes that children born by caesarean section will not survive because the birth canal is not protected.
