What is the minimum age kids must be to stay home alone? There is no national law regarding a child’s minimum age to stay home alone. A few states have set forth an age, such as Oregon (10 years) and Maryland (8 years), but the majority are either completely silent on the issue or offer only recommendations.

Wondering about when I can start to leave my self-sufficient, smart, 8-year-old daughter at home alone for about 15 minutes on a rare occasion. I would have our next door neighbor on alert and available for her to call or go to in case of emergency or being scared.

If your kids are 14, 12 and 9, your job as parent is rapidly changing from watching over them constantly to teaching them to take care of themselves. When and how to leave older kids alone at home depends a lot on the kids.

If your 10-year-old is begging to stay home alone for a few hours after school rather than go to the after-school program, you may be in a quandry over whether or not to let him.

Some kids love the idea of a few hours alone in the house, while others are paralyzed with fear at the thought. If your child is on the young side for being left alone—age 10 or 11—don't push the idea if you know they're apprehensive about it. Most authorities believe that the average 12-year-old can handle staying at home alone for a few hours, according to the Washington State Department of Social and Health Services.

Kids are ready to stay alone for a few hours at wildly different ages, depending on their maturity level, their quotient of common sense and, last but not least, the laws in your state, if any, on the legal age for leaving children without an adult present.

However, for teens older than 13 you have to think about protecting the house from the teen! We stopped going out at night if it would leave an older teen at home, because we know of local teens who will text 20 of their friends for an impromptu party.

Depends on the kid. When I was 11, I stayed home alone with 3 younger sibs. My kids are 11 now and while I trust my daughter to stay home alone, I worry my son would get into matches, etc. With so much at stake, better to err on the side of caution.

While the precise age to be home alone depends on a lot of factors, five is WAY TOO YOUNG to be alone at home, even if you are ''just ten minutes away''. A five-year-old can't possibly have the maturity, life experience, and knowledge to deal with any kind of emergency.

Maryland, for example, specifies that children must be at least 8 years old to stay alone but also lists a number of stipulations that parents should consider, such as the duration of time alone, the child's access to help and whether he understands what to do in an emergency.
