Each baby is an individual and has its own developmental rules, the degree of language development is slow and fast, some babies start talking at the age of 1, but some babies can only talk at the age of 2, and some even later, first of all, talking early is certainly a good thing, indicating that the baby’s language development is earlier, the ability to express and understand is stronger. About 10% of preschoolers who speak late are diagnosed with “delayed language development”. The causes of delayed language development are usually 1. hearing impairment. Hearing impairment can seriously affect the development of baby’s language, because the language preparation stage baby is required to imitate in the sound, children with minor hearing loss, can still watch others lip movements to learn to pronounce, serious hearing impairment is difficult to learn to speak. 2, environmental factors. For example, parents at home are less talkative or even silent, lack of language interaction with the baby, the baby lacks imitation, learning objects, such as children in charitable institutions, language development is later than the average normal family baby, because of the lack of language environment. 3, low intelligence. The language development of babies with low intelligence is later than normal babies. 4.Autism. Expressed as the baby does not like to interact with people, like to play with their own, poor eye to eye, language development is backward. It needs to be checked in a regular hospital for clarification. The early and late speech is closely related to these 3 points The early and late speech is related to the baby’s own growth and development, family environment, parenting style, etc. 1, the baby’s language development 0-1 years old: language preparation period, basically based on simple pronunciation, “babble” “ah ah oh oh”, it indicates the beginning of speech. As long as the baby ohhhhhhh, you should respond in time. 1 year – 1.5 years old: language understanding period, can understand simple words, such as you say “no” shake your head, “eat” wave, can use simple words to express their will, such as “rice rice “, “Grandma”, “eat eat”. At this time, the baby’s language can correspond to the action. 1.5-3 years old: the period of language leap, vocabulary growth, can use sentences to express their requests, although some times the narrative logic is a bit chaotic, and you will often hear your baby pick up words everywhere, maybe you said, maybe on TV. Most babies are this rule, can express themselves more clearly at the age of 2 1/2 3 years, of course, each baby has individual differences. 2, related to the family environment If in a non-stop language stimulation environment, every day with the baby nagging nagging, that baby will speak a little earlier, and will be a chatterbox + 100,000 reasons. If you think that the baby does not understand, do not interact with the baby, the baby will not be able to learn to imitate, language development will be relatively slow. So, when playing with your baby, you must put down the phone, IPAD, and talk to your baby more. 3, related to parenting research has found that the richer the language of parents and baby interaction, the more beneficial to the baby’s language development. For example: telling picture book stories to expand the richness of language; the world is so big, take your baby out to see new things; humming beneficial children’s songs, catchy melodies and so on. Don’t worry too much when your baby is talking later than other babies, be patient, praise and encourage your baby to talk more, be really worried and go to the hospital for a comprehensive assessment to find the cause and take appropriate measures.
