A baby is usually a small person between the ages of 0 to 3 years old. The only way it can communicate is by crying and making noises. A baby's number 1 ally is its mother as it is her who feeds it and give it all the care and attention it needs. Baby's are usually helpless and harmless but video games have seen its fair share of evil baby masterminds.
It's rare for a game to kill a baby or put it in harm's way.
