"The health visitor noted concerning carer-child interaction during the home visit, recording that the mother showed little eye contact or verbal response to the infant's cues."

"age-appropriate explanation"

A communication technique in which medical information is given in vocabulary and concepts matched to a child's developmental level, enabling the child to participate in their own care
