Do babies under 12 months self-wean?

大概扫了一下，你家qiqi貌似正在nursing strike:

Milestone times, such as crawling and walking, and stressful times like teething or illness can also cause baby to be less interested in nursing - these types of things are common in the second six months. Nursing strikes (when baby quits nursing suddenly) also tend to be more common around this age, perhaps due to the same factors.

我宝宝大概一个多月的时候，曾经不肯吸奶过一次，我当时都吓哭了，后来我每个小时把他抱来喂一次，过两天又恢复了。
