Question
The child is two years and two months old, can clearly call out ‘Dad’ and ‘Mom,’ but uses only um, ah, and other sounds for other words. He can also talk, and sometimes chats with close relatives, but his words are hard to understand by others; it’s just the tone, not clear in pronunciation. He has no desire to play with other children.
Answer
Hello, based on your description, it is mostly likely a sign of personality and language disorders. It is best to have an examination done and engage in more communication with the baby in daily life.
