Can children grow up to be normal after growth retardation?

In the child's functional development, mostly due to congenital factors, the longer the child's symptoms may be more obvious and more serious, and will not naturally improve. If a child's development indicators delayed 2 to 3 months or longer parents need to take their child to see a doctor in time, not necessarily because of developmental delay, there may be autism caused, need to conduct analysis and evaluation to judge.
