With a sample size of just one child, no matter how much we love her, you don't really have enough of a sample size to figure out what happens on average, but at two years old, she hasn't had an ear infection yet, so we're keeping our fingers crossed on that one.
样本只有一个孩子，不管我们多爱她， 你都不能从单一样本 得出平均的结果， 但是两岁了，她还没得过耳部感染， 所以在这一点上我们很幸运。
