Question:
My son is 2 years old and weighs 15 kg. He is very active, eats and sleeps well, and follows instructions perfectly, like putting things away or helping with chores. He even hums and sings along to songs. However, he hasn't said a single word, not even 'mama' or 'dada.' I'm getting worried because I want to hear him talk. Is this a cause for alarm, and what can I do to help him start speaking?
Answer:
Hello—I know you're worried because your little one isn't talking yet. You're doing the right thing by asking early.
Your two-year-old son (15 kg) is active, sleeps and eats well, understands directions, and even hums songs, but he isn't saying clear words like "mama" or "dada," right?
It’s very good that he understands and listens—that means his hearing and comprehension are likely fine. But by two years old, kids usually start saying some clear words. If he's not yet doing this, he might have a mild speech delay.
At home, keep talking to him often, clearly naming everyday things, reading short picture books, and singing songs together. Also, it's important to mention this to your pediatrician at the next visit—they might suggest a hearing test or meeting with a speech therapist.
You're doing great by paying attention and caring so much. With a little help and patience, most children catch up quickly. Keep going—you’re on the right track
