[Walking Dead] - Where are all of the dead kids at?

Throughout the whole series; there have only been a really small handful of dead children walking about (on screen); the little girl carrying the teddy bear in the first season, Carol's daughter and the Governor's daughter...  Is there a current in-universe theory as to why there aren't more children walking within the herds?

Most of them were eaten before turning. 

Getting eaten kills you pretty fast because of blood loss, but one can turn within minutes to hours of death. An adult's body is more for a walker to eat its way through, so it's more likely to last long enough to become a walker. But a child's body is more likely to be eaten before the moment of turning.
