+## Overview
+
+`$children` instance property removed from Vue 3.0 and no longer supported.
+
+## 2.x Syntax
+
+In 2.x, developers could access direct child components of the current instance with `this.$children`:
+
+```html
+<div ref="app" id="app">
+  <img alt="Vue logo" src="./assets/logo.png" width="25%" />
+  <my-button>Change logo</my-button>
+</div>
+```
+
+```js
+export default {
+  name: "App",
+  components: {
+    MyButton,
+  },
+  mounted() {
+    console.log(this.$children); // [VueComponent]
+  },
+};
+</script>
+```
+
+## 3.x Update
+
+In 3.x, `$children` property is removed and no longer supported. Instead, if you need to access a child component instance, we recommend using [$refs](/guide/component-template-refs.html#template-refs).
