Transitioning to the "big-girl" bed

Well, it seemed to be one of those parenting things that you plan out and then it kind of just happens on its own... I was originally planning on potty training E before moving her to her big-girl bed since the bed frame hasn't been delivered as of yet. Well, we were in her room one night and I was getting ready to put her down and she spotted the twin mattress in the corner (we were just keeping it there until the frame arrives) and said that she wanted to sleep on that bed. So, I said "okay," and we proceeded to move the glider, etc. into the middle of the room and lay the mattress on the floor in the corner. She went to sleep on it that night and every night and naptime ever since! We are thrilled that she decided she was ready for this change on her own! I was honestly dreading changing beds because she really liked the crib and pack and play and I was just sure it would be a struggle. It really has been an easy transition and she has only woken up once during the night where she got up and came to the door to get out (hoping that will not continue, ha!). Looking back, I am really glad we did this before potty training too. She has some time to get used to the mattress before the frame comes in next week, and then once she is used to that we can start to potty train and there won't be any other major changes coming that may cause her to regress. That is, outside of the baby sister on the way, haha.
