Parents of cranky babies take comfort: they can turn out to be star students in Grade 1 if they have a healthy dose of good care, according to new research.

Professors at two U.S. universities analysed data involving 1,364 children, starting at six months, and concluded that infants who cry more, are hard to settle down and do not respond well to new people and situations can develop stronger academic and social skills than babies who are easy to get along with from the start.

“Parents who have these babies who are hard to deal with can become very discouraged,” said lead researcher Anne Dopkins Stright, a psychologist at the University of Indiana.

“The results of this study suggest they should not give up, they should stick with it and their child can do very, very well, in fact better than those easy babies that they probably wish they had.”
