Smart children are now possible when two years gap is maintained between siblings. Simply give birth to the kids two years apart, claims a new study.
According to the Sunday Times, Kasey Buckles, an economist whose own children are, rather fortunately, just over two years apart in age, said that if the difference is any shorter, the reading and maths skills of the older child are dipped.
She said it is likely that the difference in academic achievement is linked to the time and resources parents can invest in a child before a younger sibling arrives, however, waiting more than two years did not increase the advantage.
Siblings with a two-year spacing include Albert Einstein and sister Maja, and Lord Attenborough and younger brother David.
"We believe this is the first time anyone has established a casual benefit to increase the spacing between siblings," the Daily Mail quoted Buckles as saying.
"The two year gap is significant because the early years are the most important in a child's development so dividing your time when the child is one is more harmful than dividing it when the child is already at school," she added.
The study has been published in the Journal of Human Resources will report.
