Trying to find a babysitter can be difficult so most bad parents allow their older child to watch the younger child Usually this would kick in when the oldest child is 13 years of age or so, but in this economy you have to grow up fast. If you youngest can still be clipped down and your oldest can’t undo that clip you should be good to go. Remember to properly child proof your house – lock up the guns, booze, and knives. I think that is all you have to worry about right? As long as all of your markers are non-toxic you should be fun. Now go out and enjoy yourself.
