Since the publication of the above paper, the authors have noticed that in referring to the weight status for 9-month-old children, the descriptor should be the CDC standard of percentile of weight-for-height, rather than the percentile of BMI. Throughout the article, any statement about ‘crossing the 85th percentile of BMI at 9 months old’ should read, ‘crossing the 85th percentile of weight-for-height at 9 months old’, and any statement about ‘crossing the 85th percentile of BMI at an earlier age’ should read, ‘crossing the 85th percentile of BMI or of weight-for-height at an earlier age’.

The authors apologize for these mistakes.
