Goat and kids recognize each other by the sound of their calls, not by their appearance. Kids suckle for a period of six months, before they begin to eat leaves and grass. Their age can be determined by their teeth. A one-year-old kid has, for example, two teeth, while a two-year-old has four teeth and is then considered adult.
Newly born domestic goat kids are able to stand immediately and to follow their mother.
