The secret to smart children is as simple as giving birth to them two years apart, a new study has claimed.
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.
