Abed is an average toddler. his parents can expect him to utter his first multiword sentence around

The answer is 21 months.

At just a little short of 2 years, you can expect a normal and healthy toddler to utter their first multi-word sentence.

For female toddlers, it might be a bit earlier but generally, 21 months is the average time.

If a toddler speaks a bit later, e.g. more than 48 months, it is recommended to go to a pediatrician for a quick check up.
