I think you no need to worry, my mom said that when I was 3 years old still say nothing ga. But after I go to school, I start to talk and since this moment, my mom say I talk too much I think your son will talk more after he go to school
My son is now 21 months old but still 不懂講話, even single word. He just keep on talking too many baby language. He is taken care by my Filipino Maid. I am afraid because of 2 languages at home. Should I talk to him in English or Cantonese to make him learn "speaking" fast? Please help.
