(单词翻译)
One of the most amazing phases in childhood development is when infants go from making baby sounds to actually saying words. Before you know it, your infant becomes a toddler and starts stringing words together into sentences. Sometimes, however, such verbal dexterity1 arrives with a troubling side of what pediatricians and speech therapists call dysfluency, or childhood stuttering. It's not uncommon2 for kids between the ages of two and three to experience normal dysfluency, which means inserting lots of "uhs" and "ums" into their speech. Sometimes childhood stuttering can also involve the repetition of words or parts of words.
