I discovered something really brilliant today! Okay wait... that's giving myself way too much credit! Let me try again - I read something and then tried it and then discovered that it works really well!
My Carschooling book said that for long trips you should put a twin sized mattress pad or fitted sheet over your car benches/seats to protect them from the obvious long-journey messes. You cut slits in them for the seat belts and then at any time you can shake them out or wash them. I think this is quite smart for ANYTIME with kids, really. So I got a fitted crib sheet that fits over the back 2-person bench (just the seat part) of our van and then used an old twin-sized fitted sheet on the middle 3-person bench and it actually fits right up and over the back too. I'll slit holes for the seat belts, position-adjusting handles as well as for the head rest poles. I think it'll save at least a little wear and tear off of the upholstery in our van. I do have a twin sized mattress pad that I might try on the middle bench. If it saves just ONE juice spill...
The thing I think is so fun about this is, if you did it just regularly (considering how cheaply you can get sheets) you could go neutral to match your car or play with all kinds of colours!
Anyway, just thought I'd share! (Did I mention we have 7 days to go? Barton leaves tomorrow morning for the next 5...)
