look in on
Stop by momentarily
To look in on someone is to make a brief visit, usually to check on their wellbeing: I'll look in on your mother while you're away.
The phrase suggests a quick, caring check rather than a formal or extended visit—stopping by to see that someone is comfortable, safe, or managing: The nurse looked in on the patient every hour.
