What's Under Your Child's Seat?

Have you checked what's under your child's seat? Are you afraid of finding out what's under? Sometimes I don't want to take the car seat off and pretend that my son is not messy. Lol!

We let him eat and play with his toys in the car especially for road trips and when it's time to cleaning the interior, we would normally find chips crumbs, Goldfish crackers, Lego bricks, a Nerf dart and sometimes some spills of his favorite chocolate milk.

First before and after photo shows years and years of neglected cleaning of this mini-van:

Second pic shows dried vomit:

So what's under your child's seat?
