新生儿是指生后四周以内的婴儿,这些婴儿睡眠时间很长(每天大约要睡二十一小时至二十二小时),怎样知道宝宝生病了呢?年轻的父母常常弄不清楚。有人把健康的宝宝抱去找医生,也有人对宝宝的疾病毫无察觉,往往延误病情。 Newborns refer to infants within four weeks after birth. These infants sleep for a long time (about 21 hours to 22 hours a day). How do you know if your baby is sick? Young parents often do not know. Someone hugged a healthy baby for a doctor, while others did not notice the baby’s illness and often delayed his illness.
