A new study just out has analysed the quality of driving among siblings - and it's bad news if you're the first born.
The eldest child, whether male or female, is significantly more likely to wrack up fines for speeding and illegal parking. They are also more likely to be involved in road traffic accidents.
And, just to put the icing on the cake for babies in the family, youngest siblings are statistically the safest. Although 17% of them admit to applying make-up while driving and 30% use their phone behind the wheel.
A whopping 89% of older siblings are more likely to speed, 47% cut people off, and 35% likelier to get fined.
The study of 1,395 motorists conducted earlier this year for Privilege Car Insurance, found that more collisions occur between eldest siblings. Hear Clairsy, Matt & Kymba's take on this morning's Big Breakfast:
