Question

A two-and-a-half-year-old boy has a habit of grinding his teeth and sticking out his tongue, and his fontanelle has not yet fully closed. He can climb stairs on one leg, but seems unsteady when running, and can only speak in two words. The parents are worried if the child is normal, although he likes listening to music and can arrange movements himself.

Answer

Based on the information you provided, the child may be showing signs of delayed growth and development. It is recommended that parents take the child to a regular hospital for a check-up to confirm the issue and seek appropriate solutions. Typically, by two and a half years old, a baby’s fontanelle should have closed, and there should be some development in language expression. It is suggested that parents consult a professional physician as soon as possible to receive accurate diagnosis and treatment advice.
