有缺憾,才是成长。如果妈妈不是剖宫产,大双是小双,小双是大双。可那经验少的年轻女医生把肚皮划开后,先把后面的婴儿抱出母体了。就这样,哥哥成了弟弟,弟弟成了哥哥。而问题的关键是,后面的个头大,6斤7两;前面的个头小,4斤3两。结果被爷爷一锤定音,说大的叫大双,小的叫小双。 There are shortcomings, is growth. If the mother is not a cesarean section, big double is a small double, small double big double. But less experienced young female doctor after the belly cut open, the first baby behind the maternal body out. In this way, my brother became younger brother and younger brother became older brother. The crux of the matter is that behind the big head, 6 pounds 7 two; front small, 4 pounds 3 two. The result was grandpa a fixed name, said big called big double, small called small double.
