True.
Explanation: Children should be able to begin combining words at 18 to 24 Months. Most toddlers can say about 20 words by 18 months and 50 or more words by the time they turn 2. By age 2, kids are starting to combine two words to make simple sentences, such as "baby crying" or "Daddy big." If the child doesn’t begin to show these around that age, things such as hearing problems, neurological problems like cerebral palsy, muscular dystrophy, and traumatic brain injury (which can affect the muscles needed for speaking), or autism could be a factor in late development.
