A little boy finds his world turned upside down

Today we are going to bring home my little girl. At the ripe old age of 3.5 my son is aware that his world is changing and a little anxious about what those changes may be. I told him that it would be ok and tried to reassure him, but I am not having a lot of success.

In any case my 3 younger sisters survived me and I am sure that little Jack will not do anything to his sister. And now I am off to do more prep work for bringing the girls back home.
