Children develop at different rates and so should be left to themselves to acquire language skills or it is such intervention justified is depends on the situation. Children have their own ability and times required to speak. Parents those are often over-anxious to teach their children to speak maybe because they don’t have knowledges about how childrens grow. They lack of informations about this and assumpt that their children have to be given to the psychologists or schools. But, if the children can’t speak until the maximum of ages, it will be the best decision.
Besides that, leaving children to acquire language skills by their own ways and abilities also correct. Children can increase their language skills by their own, such as; listening to other people conversations, watching videos, or maybe just a simple conversation with their parents before sleep. They can develop new vocabularies while having a conversation with other people.
In my opinion, children should be left to acquire language skills by themselves until the maximum of time. We can playing together with them, having conversations, reading fairy books before sleep, and learing new sports. When the maximum time has came, and the children still cant speak properly, we can give them to professional psychologist and schools to intervene and give them speech therapy. Because, they know the best way and they have knowledges about it. We can trust our child to them, and do any opinions they give to us.
Thus, learning how children grow is essential for parents before they decided to have children for a better growth.
