I don't really understand the context, but you can iterate over a Transform to have all its children:

 foreach (Transform child in transform)

So you can just count yourself:

 var childCount = 0;
 foreach (Transform child in transform)
 {
     childCount++;
 }

With this, you can implement whatever you want.

That being said, I also just checked Transform.childCount in 2020.3.17, and it only counts direct children of an object anyway, children of children are ignored.

what if i use it with a tag ? can this work ?

  for (int i = 0; i < t.childCount; i++) 
          {
              if(t.GetChild(i).gameObject.tag == tag)
              {
                  return t.GetChild(i).gameObject;
              }

Sure, why not! It would work with a foreach loop as well.

 foreach (Transform child in transform)
 {
     if (child.gameObject.CompareTag(tag))
     {
         return child.gameObject;
     }
 }

it works but i really need the childcount to be 0 or 1 cuz if its not the player can pickup 2 weapons which is not ideal is that posible to force it to be 0 or 1 ? if (transform.parent == holder && holder.childCount ==1 ) { Pickedup = true;

             }
              if (transform.parent != holder  && holder.childCount == 0)
             {
                 Pickedup = false;
             }
              else if (holder.childCount > 1)
         {
            
         }
         print(holder.childCount);

No, you cannot force a count. Your code is going in the right direction here; check whether a child already exists (`childCount > 0`) and if it does, decide what to do next. Either you refuse to pick up another item or destroy the current one.

If you there is a script on the components you want to get, you can use GetComponentsInChildren()
