The term for a baby sheep is "lamb." Lambs are typically born in the spring and are known for their soft, wooly coats and playful demeanor. They are part of a species called Ovis aries. Young lambs are generally weaned from their mothers at around 4 to 6 months old and can then be raised for various purposes, including meat, wool, and companionship. The term "lamb" specifically refers to sheep that are less than one year old, while older sheep are referred to as ewes (females) or rams (males), depending on their gender.
