My 22-month-old boy was born premature (31 weeks). I am extremely worried about his developmental delay. I am posting to see if anyone is in the same boat. He learned to point at things with one finger when he was 19 months old. He did pointing for two weeks and never did afterward. He otherwise uses his index finger on books with texture and sometimes on the glass door of the microwave oven. I tried to teach him to clap a lot but never clapped. He waves and high-fives occasionally when he wishes (maybe once a week or two weeks). He is nonverbal. Recently started to copy words we say such as cat, fish, shark, ABC, one, two, three, etc). However, he does not know the meaning of these words. Just repeats when we say. Only understands one command which is 'NO'. He stops when we say No. He was not responding to his names until recently. Recently he responds to his name 50% of the time. In some instances comes running from another room if we call by his name. His hearing is checked. Hearing is fine. I have not noticed any sensory intolerance in him. Used to flap hands too much which has reduced recently. Now, flaps sometimes (maybe once or twice a day, previously it was all the day in between play). Does not line up toys or has no obsession with anything as such. No tantrum at all. Good sleeper. Excellent eye contact. Likes to copy us such as brushing teeth, and combing hair when we do. He knows where things belong in the household. If he sees his biscuit container on the floor, he would keep that on the tabletop where it generally belongs. Cannot stack blocks yet or sort shapes on a board. But can insert a ball on the whole, can pour water from the bathtub to the bathroom floor by a mug. He can draw lines on walls or on a piece of paper. No issue with gross motor skills. His pediatrician had a telephone conversation with me and said, she believes that the baby could have autism but does not want to diagnose now. Too worried. Does anyone have any similar story or insight on this?
