Yes, JSX tags can definitely have children elements.
In fact, JSX is designed to represent a tree-like structure, where tags can nest other tags or text inside them. This nesting can happen in two ways:

• By placing other JSX elements inside a parent tag
• By embedding plain text between opening and closing tags

Example:

<div>
  <h1>Hello!</h1>
  <p>Welcome to my blog.</p>
</div>

Here, the <div> tag has two children: an <h1> element and a <p> element.
