"Look in" is an expression used to describe the action of peeking inside or entering a space briefly, usually for a specific purpose. For example, "I need to look in the fridge to see if we have any milk" means that you will quickly open the refrigerator to search for milk. Another example is "Can you look in on the children while I run to the store?" which means to briefly check on the children to ensure they're alright. This expression is often used in casual conversation informally.
