Is my child autistic?

Professionally speaking, not necessarily. Autism has special and obvious symptoms. It's not just poor language expression.

First, interpersonal communication barriers: [no attachment behavior] ignore people and play with themselves; No, (I don't stick to adults like ordinary children, I like adults to hug him and Doby to play with him). Some people describe that they regard their parents as "tools of life", and only hold their mother's hand when they want to eat (rather than "objects of affection") and ignore their mother when they are fine. [There is little difference in the reaction to relatives and strangers] Seeing that mom is coming and dad is off work, he will not be particularly happy, but he often has no reaction; I'm not afraid to meet strangers and I don't know strangers. [Not interested in interpersonal relationships] Not interested in group games, rarely actively looking for people to play, rarely actively participating in conversations with a group of people, and rarely maintaining real and lasting friendship with others. With the growth of age, some people will make progress in interpersonal relationships, but they still show the characteristics of not being interested in "people".

Ⅱ communication disorder: [Language communication disorder] commonly known as language development retardation. Many parents take their children to the hospital because their children are "a few years old and can't talk." The main manifestations are: unclear articulation, too fast speech speed, too high or too low tone; Say a single word instead of a complete sentence; Parody is obvious, such as reciting poems, advertising words, or repeating other people's questions; Difficult to talk about, such as passive answer, irrelevant answer, repeated questions, single topic; Personal pronouns are often misused, and "I" and "you" are confused. Non-verbal communication barriers: you don't need to communicate information or feelings with your eyes, and your eyes are often erratic; I can't communicate with my mother or other people with gestures, expressions and body movements.

ⅲ Stereotype behavior: [Fixed reaction to people and things] Say fixed words and do fixed actions to relatives or strangers, not knowing that it should change from person to person, from time to time and from place to place; Treat toys or certain items in a fixed way; Be dependent on certain items. There are fixed rituals in daily life, which are often manifested in saying fixed words and doing fixed actions before and after eating, sleeping, going to the toilet, going out and just coming home. These are called ritual behaviors. [self-stimulation] Many autistic children have fixed ways to use their bodies, such as squinting at people, walking on tiptoe, playing with their own voices (barking, laughing, talking to themselves), touching their lips, ears or other body parts, playing with their fingers, clapping their hands, stamping their feet, shaking their bodies back and forth, and turning in circles.

Ⅳ Abnormal reaction to the outside world: [Too weak reaction] Many parents with autism describe their children as "deaf" and "blind", so they have had the experience of taking their children to the otolaryngology department. They often behave as if nothing had happened, as if they were living in their own world forever, and what happened outside could not pollute them. [overreaction] There are also many autistic children who react strongly to some minor changes in daily life and small stimuli that ordinary people don't agree with, such as covering their ears with their hands, as if they can hear sound stimuli that others can't feel, and some people are too excited or afraid of certain smells, colors, shapes and textures.

You should seriously feel and evaluate these aspects. At least most of the same problems should be taken seriously. Other problems may be related to family education.
