We have a Britax Super Cruiser (I looked for a link but they seem to be discontinued now) for David. He does throw up from time to time (all the bends on our roads I guess) and you can take the entire outer coating off and it's machine washable. I'm not sure how we would have managed otherwise.

We had a Volkswagen a few years back that we nicknamed the Vomitvagen on account of repeated distasteful expellations. We put an awful lot of perfume in that car in order to sell it.

Both the girls were sick in the car too when they were younger.

Maybe it's my driving!
