Does it only loop in the paren'ts children or in all of the gameobjects in the scene ?

In Unity, the hierarchy information is stored in the Transform component rather than the GameObject itself. You can find a child with a given name using the Find method on the Transform:

 GameObject GetChildWithName(GameObject obj, string name) {
     Transform trans = obj.transform;
     Transform childTrans = trans. Find(name);
     if (childTrans != null) {
         return childTrans.gameObject;
     } else {
         return null;
     }
 }

Thank you for your answer . Does your solution only loop in the paren'ts children or in all of the gameobjects in the scene ?

Even better :

 public static GameObject GetChildWithName<T>(this T obj, string name) where T : Component
         {
             Transform trans      = obj.transform;
             Transform childTrans = trans.Find(name);
             
             if (childTrans != null)
             {
                 return childTrans.gameObject;
             }
 
             return null;
         }

Edit : If you need deep (more than 1 children down) : https://answers.unity.com/questions/799429/transformfindstring-no-longer-finds-grandchild.html

Place this code on parent object:

 foreach (Transform eachChild in transform) {
     if (eachChild.name == "NameWhatYouNeed") {
         Debug.Log ("Child found. Mame: " + eachChild.name);
     }
 }

Update: Method above is better. Didn't know that.

You would actually use

transform.GetChild(yourIndexHere);
