Can a 8 year old be left with a 2 year old at night?

Leaving an 8-year-old alone with a 2-year-old at night is generally not advisable. While the 8-year-old may have some responsibility and understanding, they may not be equipped to handle emergencies or provide adequate supervision for a toddler. It's important to consider the maturity of the older child, the specific circumstances, and local laws regarding childcare. Ideally, an adult should always be present to ensure the safety and well-being of both children.
