Weighing more than your twin at birth may predict better achievement at school

Research has shown that children who are born at a low birthweight are less likely to do well in school and more likely to live in lower-income neighborhoods as adults. A new study of twins looked at the effect of birthweight on children's cognitive and socioemotional outcomes at 4 years old, taking into account families' socioeconomic status (SES). The study showed that weighing more than your twin before starting school may help with achievement. It also found that socioeconomic status accentuates the effects of birthweight on early development.
