How to find the first child serializedProperty inside a PropertyDrawer

I would like to find the first child property inside a a PropertyDrawer. In my current code I get value of the first enum to use as a label, but I need explicitly find the child property by name

how to find first property in a property drawer

[CustomPropertyDrawer (typeof (TempleIdleGenerator.RaceSlotItemFreq))]
public class RaceEnum : PropertyDrawer {
	public override float GetPropertyHeight(SerializedProperty property, GUIContent label) {
		// use the default property height, which takes into account the expanded state
		return EditorGUI.GetPropertyHeight(property);
	}

	public override void OnGUI (Rect position, SerializedProperty property, GUIContent label) {
		EditorGUI.BeginProperty (position, label, property);

		// Draw label
		var labelProperty = property.FindPropertyRelative ("race");
		int index = labelProperty.enumValueIndex;
		label.text = labelProperty.enumDisplayNames [index];
		EditorGUI.PropertyField(position, property, label, true);
		EditorGUI.EndProperty ();
	}
}

[System.Serializable]
public class RaceSlotItemFreq{
	public Race race;
	public List<SlotItemFreq> slotItemFreq;

}

I would like to replace the phrase
property.FindPropertyRelative (“race”)
with something that finds the first child.

Final code here

[CustomPropertyDrawer (typeof (TempleIdleGenerator.RaceSlotItemFreq))]
public class LabelEnum : PropertyDrawer {
	public override float GetPropertyHeight(SerializedProperty property, GUIContent label) {
		// use the default property height, which takes into account the expanded state
		return EditorGUI.GetPropertyHeight(property);
	}

	public override void OnGUI (Rect position, SerializedProperty property, GUIContent label) {
		EditorGUI.BeginProperty (position, label, property);

		// Draw label

		var tempProp = property.Copy();
		property.NextVisible (true);
		int index = property.enumValueIndex;
		label.text = property.enumDisplayNames [index];
		property = tempProp;

		EditorGUI.PropertyField(position, property, label, true);
		EditorGUI.EndProperty ();
	}
}

You probably want SerializedProperty.NextVisible()

property.NextVisible(true);
