1、大腦皮層抑制功能差
嬰幼兒的大腦皮層抑制功能較差。在他們?nèi)朊吆螅竽X的某個(gè)區(qū)域可因一些因素（如睡前過度嬉戲打鬧；受到驚嚇；剛進(jìn)入陌生環(huán)境等）仍保護(hù)興奮狀態(tài)。在這種情況下，寶寶就容易從淺睡眠中驚醒，有時(shí)還因此而產(chǎn)生夜驚和遺尿現(xiàn)象。

In this case, it is easy to wake up the baby from light sleep, sometimes resulting phenomenon of night terrors and enuresis.
2、夜間進(jìn)食
8個(gè)月以后的寶寶一般不需要在夜間喂食了。但有些父母以為孩子夜里哭鬧一定是饑餓難忍，于是忙著喂奶、喂水。結(jié)果等寶寶再次睡著后，他/她的消化系統(tǒng)卻不得不開始“加夜班”，引起副產(chǎn)品--排尿增多，這使得寶寶再次從睡眠中醒過來。

有些父母在寶寶每次驚醒后，都立即又搖又抱；甚至陪著他玩、陪著他睡，以這些方式哄孩子入睡。反復(fù)多次后，給寶寶建立了不良的條件反射，每次醒來后都渴望有同樣的“待遇”；一旦不能得到滿足，就覺得特別委屈而大哭大鬧不止。

After repeatedly, bad for the baby to establish a conditioned reflex, each eager to wake up the same "treatment"; once can not be met, I felt particularly aggrieved and wailed beyond.
4、困難型氣質(zhì)
屬困難型氣質(zhì)的寶寶較難建立正常的吃、睡和排泄的生物切律。常常在無饑餓、尿布干爽或無疾病，甚至在細(xì)心照料下仍會(huì)無端哭鬧，使父母常感束手無措。
