My son doesn't have many words and we're at almost 20 months. Maybe 20-25 words total, most not very clear. We were a little concerned at his 18th month checkup because he seemed to have less than 10 words but the doctor didn't seem too worried. He understands way more than he speaks though. He can follow pretty complex commands. The other day I was getting dinner out of our pantry and he followed me in and grabbed a box of his cereal bars off the shelf. I told him to take one, put the box back and go to his high chair and he followed it exactly. Like Ao- I feel doctors might be too broad with the autism diagnosis, kid not talking, thats autism, kid not pointing, thats autism.
