Some parents do not think their children can speak at the age of 1-2 years old, thinking that they will naturally speak when they are older, or even that “your people are late in speaking”. It is true that some children’s “late speech” is normal and does not require special treatment, but this is after all a minority of cases. 2 years old still speaks very little is to raise alarm. There are also cases where the child’s tongue tie is too short and requires an examination. In fact, a short tongue ligament does not usually affect how early or how late the child speaks, but only the clarity of speech and only the articulation of the curly tongue. Language is a tool for communication, and children’s language develops gradually and in a certain order. Although there is a great deal of variability in language among children, the age at which a group reaches a certain level of language is the same. In other words, there is an “age of speech” phenomenon. Children begin speaking as early as 9 months of age, and at least 95% of children can speak by 18 months of age. The average age of first meaningful words is 12 months. 1-5 years old language development chart 1 year old: 1, instinctive crying, cry response to different stimuli 2, smiling response to sound 3, able to determine the direction of the sound, and can turn the head to the sound 4, able to distinguish between a number of different sounds 5, see food to eat response 6, yada yada pronunciation, able to make a variety of sounds 7, able to pronounce two sounds (such as: mother, big) 8, murmur 9, listening to music appeared to be happy 10, listening to music appeared to be happy, Appears happy when listening to music 10.Appropriate response to words and gestures (e.g., can wave when saying goodbye) 11.Can make some simple requests (e.g., grab the ball) 12.Can use gestures or gestures to express requests 2 years old: 1.Can imitate the sounds around him 2.Can imitate two simple words 3.Can point out a part of the body when asked 4.Can take the initiative to say two words of simple words 5.Can point out what shoes, clothes or toys are 6.Can speak five words 7.Can point out three different things in a picture book 8.Can speak individual words that he hears 9.Can name three wishes when asked what he wants 10.Can name three things that happen around him when asked 11.Can speak a two-word phrase 12.Can turn and look at a picture book 3 years old: 1.Can name two occupations (such as Mom is a teacher) 2.Can answer “What is your name?” 3. can name four or five objects in front of him/her 4. knows “big” and “small” 5. can say three-word sentences 6. can repeat two numbers 7. can name more than forty items 8. can use “I” or “we”, “my” 9.

If the child understands and responds appropriately to every call or instruction from parents or others, or can complete most tasks according to verbal instructions, and is no older than 2 years old, the child can be observed for a while longer and given enough language stimulation to promote early speech. If the child is still unable to speak or speaks minimally beyond 2 years of age, an assessment of language development and the necessary interventions and home training are recommended. Once the presence of a disorder is confirmed, early treatment can restore some or even most of the speech. For example, audiological testing is now available at 3 months of age to make a definitive diagnosis, and once diagnosed, early rehabilitation can help restore some auditory ability and lay a good foundation for future speech.
