There's not much you can tell Caroline about children she doesn't know and hasn't seen. She's unflappable and takes it all in her stride. She will hit the ground running no matter what state you're in whilst trying to leave and calmly takes over. My children love her and look forward to her visits so no guilt trips for leaving them at home! Caroline always brings a little toy or book or plays a game with them. All is peace and order when we return. Highly recommended.
