【Objective】 To acknowledge the natural physical growth pattern of exclusively breastfeeding infants in capital Cities and to provide the reference for growth monitoring and nutritional evaluation. 【Methods】 According to the WHO 2006 growth monitoring project, 1 343 exclusively breastfeeding infants were recruited in six capital cities in China. The longitudinal weight, length, and head circumference were measured from the birth to 12 months old. The monitoring frequency was 16 times in total. 【Results】 Compared with birth weight and height, the weight of infant was 2 times after 3 months old and 3 times at 12 months old, and the length was 1.5 time at 12 months old. The value of weight, height and head circumference was higher in boys than in girls, and the difference was significant(P<0.01). Compared to WHO 2006 new growth standard, the weight, height and head circumference value was higher in our capital cities breastfeeding infant, except for seven days and fourteen days. 【Conclusions】 The growth and development status of six capital cities breastfeeding infant are in good condition. The growth potential of infants in capital China achieved WHO 2006 new standard.
