Changing sleep patterns

I'm so proud of Emily. She went to sleep all on her own like a big girl without mommy rocking her to sleep! We've been having trouble getting her to go to sleep before 2:30 in the morning. We used to rock her to sleep with noise in the background, the lights on, etc. This time, we tried something a little different. We turned off the lights, turned off the TV, swaddled her tight, turned on her sound machine, and laid her down without rocking her to sleep. She was asleep within 5 minutes and stayed asleep for nearly 5 hours straight!!  I can't believe it. She's such a great baby. It'll be so nice to get her on a normal sleep schedule again.
