Specific performance: fifteen-month-old babies are equivalent to more than one year old, this period of time the baby’s language development, motor and physical development, reaction ability, cognitive ability and so on have a relatively good development, will understand the adult’s expression, will be able to walk independently and sit up, will recognize a lot of things and so on. Parents can pay attention to observation for judgment.
2. Intelligence assessment: If parents cannot judge whether their baby’s intelligence is developing normally, they can go to the hospital for a professional intelligence assessment test to determine whether their baby’s intellectual development is lagging behind that of other children of the same age.
