Which factor is commonly linked to slower growth or motor development in infancy?

• A. Being a twin, born preterm, and having a teen mom
• B. Regular exercise during pregnancy
• C. Adequate prenatal care
• D. Balanced nutrition

Answer: (A)

Infancy growth and motor development are shaped by birth conditions and the prenatal environment. Twins are more likely to be born preterm or with low birth weight because they share the womb, which raises the risk of delays in reaching motor milestones due to the brain and nervous system not being fully ready at birth. A teen mother adds to these risks through factors like reduced access to quality prenatal care, fewer resources, and higher stress, all of which can contribute to preterm delivery or low birth weight, again increasing the chance of slower growth and motor development in infancy. By contrast, regular exercise during pregnancy, adequate prenatal care, and balanced nutrition are protective, supporting healthier growth and motor outcomes rather than delays.
