Twenty-seven 5--8-day-old babies were filmed during normal breast feeding (one feed each). Sucking patterns were determined from the film from a total sample of 17,676 sucks. Intersuck interals fell on two distributions: one of intervals between sucks during bursts of sucking (1.3 sec and less), and the other of rests between bursts of sucking (1.3 to greater than 12 sec). As the milk flow dropped towards the end of the feed on each breast, the sucking rate within bursts increased (P less than 0.05), but there were more (P less than 0.001) and longer (P less than 0.001) rests between bursts of sucking. This study provides normative data on a normal population for use in studies of breast feeding.
对27名5至8日龄的婴儿在正常母乳喂养期间（每人一次喂养）进行了拍摄。从拍摄的影片中，在总共17676次吸吮样本中确定了吸吮模式。吸吮间隔呈现两种分布：一种是吸吮阵发期间的吸吮间隔（1.3秒及以下），另一种是吸吮阵发之间的停歇（1.3至大于12秒）。随着每侧乳房喂养接近尾声时乳汁流量下降，阵发内的吸吮速率增加（P<0.05），但吸吮阵发之间的停歇更多（P<0.001）且更长（P<0.001）。本研究提供了正常人群的规范性数据，以供母乳喂养研究使用。
