A new study has revealed that not only is it true that first-borns are generally smarter than their other sibling, but that it’s because parents do pay more attention to them!
In order to explain the "birth order defect" and why some children born earlier in the family get better education and make more money, the study authors analysed a whopping 5,000 children from birth to the age of 14.
The children were assessed and given reading, letter-matching and picture vocabulary tests every two years, and astonishingly found first-born children had higher IQ scores than their younger siblings by the age of one.
The study revealed that while all the parents with multiple children gave all their kids the same levels of emotional support, first-borns received greater levels of intellectual support, which in turn improved their thinking skills.
The results also showed parents did less brain-boosting activities with their younger kids like arts and craft, playing musical instruments and reading to them.
Is this true for you family?
