What can hinder a child's success in a developmental domain?

Delays in optimal learning periods can significantly hinder a child's success in a developmental domain because certain stages in a child's life are conducive to acquiring specific skills. These critical or sensitive periods are times when a child is particularly receptive to learning certain information or behaviors. If a child misses these optimal windows for learning, they may struggle later on to develop essential skills, such as language acquisition or social interaction.

For example, if a child does not have sufficient opportunities for social interaction during early childhood, they might experience delays in developing communication skills or understanding social cues, which could affect their future relationships and academic performance. This concept emphasizes the importance of timely and appropriate experiences in a child’s development, as the absence of such experiences during these crucial periods can have lasting impacts.
