What are the symptoms of growth and development delay?

Symptoms of delayed growth and development primarily include children significantly lagging behind their peers in physical growth indicators such as height, weight, and head circumference. Specific manifestations may include slow height growth, lack of weight gain or slow weight increase, and a smaller-than-average head circumference. In addition, motor development may also be affected, such as delayed achievement of milestones like sitting, standing, and walking, as well as delayed fine motor skills. In terms of language development, problems may include unclear pronunciation, limited vocabulary, and poor expressive abilities. Intellectual development delays may also be present, characterized by low learning ability, slow responsiveness, and difficulty concentrating. These symptoms may occur individually or simultaneously. Parents should closely monitor their child's growth and development and seek medical evaluation promptly if any abnormalities are noticed.
