A couple of weeks ago we took down Abbey's crib and put in her "Big girl bed" with her new Tinkerbell bedding. I took one last picture when she woke up that morning of my baby in her baby bed.
Then at the end of the day I took pictures of her new room with her new bed. She cried a little the first night, unsure of her new room, but after about thirty minutes and reassurance that it was still her same room, she went right to sleep. She has slept great in her big girl bed every since.
