Baby cough back patting first of all to use the empty palm, and then pay attention to the strength of the bottom-up back patting, 8 to 10 times a day or so, each time as far as possible to control in 5 minutes to 10 minutes or so. The first thing parents should remember is not to use the whole palm of the hand to shoot up directly, but to arch the palm of the hand, and then gently pat the baby’s back from the bottom up. Some parents may be more anxious, think the frequency of patting to be high better, in fact, do not need too high frequency, a day patting 8 times to 10 times or so, each patting frequency control in 5 minutes to 10 minutes or so. Baby cough back patting strength must be light, to avoid unnecessary injury to the baby’s spinal parts.
