Tonight we did the deed. We inserted a crib into Gabby's room, and told Ellie, that she is now sharing the room. Gabby had no issue, and Ellie was excited. It sure is great that they get along so well. Now, I hope that the morning and overnight go well. We instructed Gabby to leave her room when she wakes up, if Ellie is sleeping, and told her she can play in the playroom. My fingers are crossed!
