Question
A 15-month-old baby, who experienced oxygen deficiency at birth and received treatment with neurotropic drugs, had low activity levels and appetite during infancy. At four months old, the baby’s head movement was unstable and received medication that affected the brain nerves and extensive physical rehabilitation training. Since then, gross motor skills have been normal. However, the baby has not yet started speaking or showing any desire to express language. Although the understanding ability is good, the learning speed is slower, and the will is weaker. Examination has found slight delay in myelination. How should treatment be approached?
