Can a child that is older watch a younger sibling in Washington State?

In Washington state, there is no specific law that defines the minimum age at which a child can be left in charge of a younger sibling. However, it is generally recommended that the supervising child be at least 12 years old, depending on their maturity and ability to handle emergencies. Parents are ultimately responsible for ensuring the safety and well-being of their children, so they should assess the situation and make decisions based on their child's capabilities.
