It is impossible to tell exactly how old a baby will be when he or she starts to talk, and it depends on his or her specific situation. Generally speaking, a normally developing child can express himself or herself simply and speak at the age of 10 to 12 months.
In fact, children do not learn to speak at once, and their language development is a gradual process. 3 months, children can make babbling sounds; around 5 months, they can simply make single words or syllables; around 7 months, they can learn to call “dad”, “mom” and other plurals, and can understand their own names. Around 7 months of age, children can learn to call “daddy” and “mommy” and understand their own names.
There may also be children with delayed speech, which may be related to the child’s own situation. As long as the delay is short and other development is normal, it is generally normal; however, if there is too much delay in opening the mouth to speak, it is important to consider whether there is a language developmental disorder, and if necessary, parents should send their children to hospitals to avoid delays in their condition.
