Can a 12 year old be left alone in Maryland?

Eat case and individual are seperate,as I know there is no set age to say when a child can be left alone.The red cross says that when a child is old enough to babysit,they are old enough to be left alone and offer courses,some children mature more and faster than others.I have ran a daycare and been asked that by several friends,it is no set law in any state.Just watch out for neighbors if your not getting along or things like that.I have been left alone at age 10 and had no problems and even babysat neibhbors children for the weekend alone at age 10 too,I would say each kid is different,I know some 19 year olds who party and do crazy things,even at any age when no one is around.I would feel as a parent,when you feel comfortable leaving them,start off for short trips out then extend it,and always leave a number and info of someone they can go to in a case of trouble,as well as they should know the general use of the stove,microwave and appliances. most times a parent feels their child can be left alone and it's a nosy neighbor with a grudge who can cause a problem or something like that,so if any questions come up like say they call child welfare protection services or whatever,make sure you cover your bases and know that they know all of your info like cell# and where your goping,etc before you gom,because if your gone and they open the door for the police a child is not going to object to them question them,so make sure they know where your going,when you'll be back,etc.
