At what age do children usually start talking?

Babies usually talk at about one year old.

Generally, babies can laugh when they are 3 months old. At 6 months, the baby can respond. At 7 or 8 months, you can unconsciously pronounce some dada and mama sounds, and at 9 months, you can welcome guests and say goodbye.

At the age of one, I can consciously call my parents, and at the same time I can say some other simple words. When I was one and a half years old, I could say some simple words. At the age of one and a half to two, most children can say some simple sentences. At the age of 2-3, their language development is further enriched, and they can speak some nursery rhymes and relatively long and complicated sentences.
