In fact, the world already hit "peak child" some years ago. The number of children in the world has stopped increasing. That means that the world's population is now only growing because of life expectancy increases and not because of increased numbers of people being born. The population will continue to grow for a while because of developing countries' life expectancy catching up with developed countries, but unless there are drastic technological breakthroughs to improve life expectancy beyond where developed countries are now, the world population will stop growing fairly soon.
