A study shows it's because boys tend to live at home longer.
Sons cost their parents almost €23,000 more than daughters.
A new study shows it's because boys tend to live at home longer. Boys tend to live at home until they're 26, whereas girls fly the nest at the average age of 22.
That four year difference adds up to a whopping €23,000 bill for parents.
Meanwhile, 20% of parents refuse to take any money from their children to help pay the bills. Some parents said they even dipped into their pension pot or worked extra hours to help pay for bills racked up by their adult children.
The average adult child living at home costs parents €470 per month for food, bills and handouts.
