Poor Vivi was so sick in the weeks before Christmas, but she did manage to help with the gingerbread house. At first Adeline resisted Vivian's help, as Adeline wanted to do it in an orderly and precise way and Vivian wanted to do it like a two year old, but with just a little reminder, Adeline was able to be very gracious about it and they really worked together to make the house. I love to watch them work together and cooperate. Sometimes the four year age difference can be a challenge, but they really do get along so well. They both had a lot of fun and remarkably ate very little candy, and we've enjoyed our little house all through Christmas.
