Hi K.,
I know it is so hard to listen to them cry, but my advice is that you're going to have to quit going into her room...if she knows you are going to come in every 5 minutes to pat her back she is going to keep it up. If she goes to bed for you without crying, you have half the battle won. Habits happen so quickly, and they are so hard to break sometimes, but I would say since you've had her ears, nose and throat checked out and she is okay you could train her again without feeling there might be something wrong...especially since she is going down without a problem. It is not unusual that they try every so often to see if they can change their schedule, but once you know there is nothing wrong, you need to be consistent and follow through. Hang in there!!!
