What happens to your baby's developmental delay

The baby's developmental delay will be manifested as backward performance in action and speech compared with children of the same age. For example, the baby will not look up at three months, sit unstable at nine months, and will not speak at two years old. A certain developmental index delay of 2~3 months can be judged as backward development. Parents can take their children to see a community hospital for physical examination evaluation and early intervention.
