We've just been on a car journey and as I wrote here a couple of weeks before we left, we had bought these dvd players for the car journey. They were used and did their job to keep the princess and little man entertained. It did nothing for them getting an achy bottom from sitting in the car hours at a time though. Well, we did do short stops quite often and every time I told them to shake their bottoms! It did help but looked silly though but who cares. The daddy on the other hand thought he'd put more action into it..... Not a bad idea at all!
