Updating firebase database (iOS, swift) with multiple fields without overriding existing data

This has been answered with reference to updating single fields but not multiple fields.

When a user registers in my app I write to firebase database a list of fields. The root of the firebase database is users and each user node is a specified unique username.

-users
     -username  
        "name"
        "title"
        "date of birth"
        "location"
        "about"
        "height"

In UpdateDetailsController is a user update page where they can update some of these fields:

 let key = model.ref.child("users").child(currentLoggedInUser).key

     let post = [
                        "name": name.text!,
                        "title": title.text!,
                        "about": about.text! ]
            let childUpdates = ["\(key)": post]

            model.ref.updateChildValues(childUpdates)

While the username remains the same using ref.updateChildValues(childUpdates) overrides the whole node so it looks like:

 -users
         -username  
            "name"
            "title"
            "about"

Advice would be appreciated!

Thx.
