No Booster Seat

This goes back to about a month ago - just getting around to posting.  And yes I took these photos while driving, but as you can see it's not the only law I am breaking.  Notice the toddler climbing into the front seat with his brother!  OK, so I thought since he is big enough, weighs enough, and old enough it might be time to switch to the booster seat.  Wrong!  Climbs himself right out.  Looks like I am going to have to find a five point harness car seat for a monster size child.  By the way this all happened less than 1/2 mile from home.  So I was driving slow and simply drove home.  I would have obviously pulled over if not for being feet from our last turn. Thankfully we were close to home - because I can only imagine how many times I would have had to pull over to put him back in - he was definitely stuck in a defiant I want to do it my way streak!  Now that some time has passed we might try again on shorter trips - but I will have the other seat in car as back up!
