I really wish I'd brought seats with a back and a heat rest instead of the booster seats because when my girls fall asleep the end up almost lying across the back seat which is obviously dangerous if I were to have an accident.
I vaguely remember seeing something that goes over the back of the car's headrest to support them a bit more but can't think where it was.
Any ideas anyone because we're off on a long journey on Friday night and they are bound to fall asleep.
