蜂蜜里面有肉毒杆菌孢子，对一岁以下婴儿有中毒的危险

Although honey seems like a wholesome and natural food to give your infant, don't do it until after she's at least 12 months old. Honey can contain spores of a bacterium called Clostridium botulinum, which can germinate in a baby's immature digestive system and cause infant botulism, a rare but potentially fatal illness.
