Sleeping through the night

Emily is 14mo. old and still does not sleep through the night. For a few weeks now I have been able to pat her back for a few minutes and she'll go back to sleep. Between 11pm and 5am this occurs about 3 times. This morning I rolled over and realized it was 6am and I hadn't gotten up once and neither had Kory. As Kory was getting ready for work I asked him to go check on her just to make sure she was still breathing. Kory came back chuckling. He told me I needed to go look at the girls. This is what he had discovered. Maybe she did wake up but this would be why I didn't hear her during the night.
