嬰兒出生后身體所有的器官和感官都在爭(zhēng)取發(fā)育，但畢竟發(fā)育速度不同，所以在個(gè)體表現(xiàn)上還是會(huì)有差異。最讓寶媽好奇的就是嬰兒什么時(shí)候有味覺(jué)，味覺(jué)可以幫助嬰兒分辨食物的味道和細(xì)小的改變，可以說(shuō)是嬰兒最基本的生活能力。那么嬰兒是生來(lái)就有味覺(jué)的嗎？還是在后天發(fā)育出來(lái)的味覺(jué)呢？嬰兒什么時(shí)候有味覺(jué)呢？下面就給媽媽解釋分析一下嬰兒味覺(jué)誕生和發(fā)育的來(lái)龍去脈。

嬰兒什么時(shí)候有味覺(jué)

經(jīng)過(guò)醫(yī)學(xué)研究發(fā)現(xiàn)，嬰兒的味覺(jué)是與生俱來(lái)的，但是并不敏感，只能區(qū)分簡(jiǎn)單的味道，對(duì)食物味道沒(méi)有記憶，沒(méi)有辨別能力，也沒(méi)有對(duì)食物細(xì)微味道改變的感受能力。醫(yī)學(xué)研究發(fā)現(xiàn)嬰兒味覺(jué)是從胎兒時(shí)期開(kāi)始發(fā)育形成的，在胎兒孕4-5個(gè)月的時(shí)候，味蕾開(kāi)始發(fā)育，具有味覺(jué)，并逐漸提升味覺(jué)的范圍和敏感度直至出生。

雖然嬰兒出生就有味覺(jué)，但是從嚴(yán)格意義上說(shuō)，嬰兒從出生后4-5個(gè)月開(kāi)始具有完善、靈活的味覺(jué)。嬰兒在出生4個(gè)月開(kāi)始味覺(jué)逐漸敏感，能夠分辨味道的不同，可以對(duì)食物味道的細(xì)微改變有所察覺(jué)，并且能夠做出反饋，直到嬰兒10個(gè)月左右的時(shí)間，味覺(jué)已經(jīng)完全就完善，十分靈敏，能夠體察到絲毫的味覺(jué)變化。

也就是說(shuō)嬰兒從出生就有味覺(jué)，在4-10個(gè)月期間是完善靈敏高峰期，在10個(gè)月之后嬰兒味覺(jué)便十分靈敏。那么在嬰兒完善味覺(jué)高峰期的時(shí)候，寶媽需要注意什么呢？

如何促進(jìn)嬰兒味覺(jué)發(fā)育

按時(shí)刺激味覺(jué)，味覺(jué)雖然會(huì)自己發(fā)育，但是想要嬰兒味覺(jué)發(fā)育的快、發(fā)育的好，就要按時(shí)刺激，隨著嬰兒月齡增加，多給嬰兒嘗試一些酸和甜的對(duì)比味道，比如用筷子蘸取水果汁給嬰兒吃，這樣有助于嬰兒味覺(jué)的快速發(fā)育。除此之外，在刺激味覺(jué)的過(guò)程中可以和嬰兒對(duì)話、溝通，加強(qiáng)嬰兒對(duì)味道的記憶和感受，能夠快速讓嬰兒感受味道的變化，但要注意味覺(jué)刺激不能過(guò)量，給嬰兒味蕾增加負(fù)擔(dān)。

通過(guò)上述分析，相信媽媽都已經(jīng)知道，嬰兒在出生就有味覺(jué)，只是沒(méi)那么靈活敏感罷了。而且只要寶媽注重口味的變化，在嬰兒1歲之前，味覺(jué)都應(yīng)該發(fā)育完善并十分敏感；如果嬰兒有對(duì)味道不敏感或是對(duì)味道小轉(zhuǎn)變不敏感的現(xiàn)象建議媽媽帶嬰兒及早做檢查，確定味覺(jué)發(fā)育情況。
