How can I target a specific node?

My setup is below.

It is working, I just have a small issue with it. Currently its checking for child notes that are text (node.nodeType === 3). The problem is, sometimes there are f.e. links or the text is strong in the paragraph and they are getting removed too.

Basically what I want to do is: target (count) everything in a paragraph that is NOT a break. Or in other words something like this: if(node.nodeType !== br)

An Example would look something like this:

<p>
  "Text"
  <br>
  <br>
  <strong>
  "Text2"

Currently the script would look at the 3 elements between the two texts and would remove the strong element from Text2 but that is not something I want. It should only count the paragraphs and nothing else.

Can somebody help me out please?

const mediaQuery = window.matchMedia('(max-width: 468px)')
// Check if the media query is true
if (mediaQuery.matches) {
  const paragraphs = document.querySelectorAll("p");

paragraphs.forEach( elem => {
  const nodes = [...elem.childNodes];
  nodes.reduce((count, node) => {
    if(node.nodeType === 3) {
      const isEmpty = node.nodeValue.trim().length === 0;
      return isEmpty ? count : 0; 
    }
    count++;
    if (count>2) node.remove();
    return count;
  }, 0);
});
  
}
