Which is a key sign that may indicate a child is in a state of developmental regression?

Losing previously acquired skills is a key sign that may indicate a child is in a state of developmental regression. This phenomenon can manifest in various ways, such as a child who previously could speak in full sentences suddenly only using simple words, or a child who had been toilet trained regressing to bedwetting. This regression often signals underlying issues such as stress, trauma, or medical conditions that may need to be addressed.

In contrast, gaining weight rapidly does not typically correlate with developmental regression; it might reflect normal growth patterns or dietary changes. Starting to sleep through the night is generally considered a developmental milestone rather than a sign of regression. Similarly, exhibiting new vocabulary indicates growth and progress in language development, contrasting sharply with the concept of regression. This context reinforces why losing previously acquired skills is a significant indicator of a potential problem in a child's development.
