Guaranteeing a story to be told over and over again when the girl becomes a teenager and asks for driving lessons, her 32-year-old mother said a huge kick from the baby caused the accident.
Swiss police said the woman was driving along a country road near Basel on Thursday afternoon when the sharp kick in her side caused her such pain that she lost control of the car.
She veered off the road, hit a lamppost, causing the car to turn on its side and career into a garden fence where it came to a halt.
The car was so badly damaged that a passer-by had to help the woman get out through the boot of the car.
She was slightly injured and taken to hospital for checks – the baby was perfectly alright, which is more than can be said for the car.
