You are correct! Children with developmental delays are those who have a significant lag behind norms in at least one developmental area. There are various areas of development, including cognitive, physical, language, emotional, and social development. If a child is not meeting the typical milestones or is significantly behind in one or more of these areas, they may be considered to have a developmental delay. It is important to note that developmental delays can vary in severity and can be caused by various factors, including genetic or environmental factors. Assessing and addressing developmental delays is crucial in order to provide appropriate support and interventions for children. Well done!
