His knees were covered with children

Description

His knees were covered with children

sounds unusual and likely incorrect unless it’s meant metaphorically or humorously. If you’re trying to describe a scene where children are sitting on or around his knees (like in a warm or playful setting), a clearer and more natural way to say it would be:

✔ Corrected versions:

• “He had children sitting on his knees.”

• “His lap was full of children.”

• “Children were gathered around his knees.”

• “He was surrounded by children, some sitting on his knees.”
