Nowadays parents have a great number of problems with their kids. Especially when they leave children at home even not for a long time.
Parents must understand when children are old enough to stay at home alone or with brothers, sisters. Sometimes mother must leave her kid for one or two hours between school-time and her work. So, the main problem is to decide when you can give a door key for your child. At the age of nine years, kids could take care of themselves, but in fact you can’t calculate all the different nuances that can grow into the big problems. Every modern house have an alarm-system. But don’t be so sure to electronics. At first you must set some rules about situation when no-one is home. Phone calls is the very important thing. They must call you if they came from school etc. Accordingly, you must give a call when you are leaving the work or the store. Try to teach them to never open the door. They only may open to grandma or other relatives.
But children must keep out from strangers. It will be better when you talk with children about all the situations that may happen and explain that no-one can enter our house. Every child must know the place where medicines are, and how to use it. Children of young age are interested in all kind of things. Please don’t put alcohol drinks on prominent places. Such things must be locked at all. Make sure your child willn’t be hungry alone. You can simply leave a snack, for example pack of chips or some kind of fast food.
So you must be careful with kids and try to avoid situations when they leave alone until they grow up.
