Safety for the numbers

Another large family, broad age spread issue which I struggle with is the safety of the youngest kids when mom is away.     The older kids do tend to become immune to where the little ones are if mom has an appointment or is taking another kid to an appointment.   Tomorrow I am going to pick up my daughter for the weekend from college and the safety of my youngest two is of course of the utmost.   The older ones do fine together.    I am considering letting go of my ideas of the TV being a bad thing and going and getting a in van TV set up.   I found one for fifty but have no idea how to hook it up.    Driving long distances with potentially screaming children is also not a safe thing.   I wouldn't be surprised if all the younger kids will want to come with if I figure out how to do this.   It was just another inspirational moment of how to survive this large family thing without taxing my nerves more than they are already taxed.   My perfect parent syndrome can stand in the way sometimes.   Hopefully I can figure out how wise this decision is in the next 24 hours.
