汤匙 = soup spoon or tablespoon, the larger kind. A teaspoon is most probably what you want and it is 茶匙 which is now used as standard in recipe books.

生活中用勺子 书面语言用汤匙 都可以的 nice to meet you , I want to learn english ,and I can teach you chinese .my Mechat number is f443884775.....I hope we can help each other

汤匙基本口语中很少出现 勺子，勺儿，小勺儿 这几个最常用 餐馆也可以说“请问勺儿在哪里？”

a small (dessert) spoon should be 小勺儿 in Chinese

small spoon is translated 小勺 literally, and we always use this calling in our life, or sometimes 汤匙 is more written on label of medicine bottles. Both of them are only described the smaller one. But ladle is meant the longer than spoon.
