Sleep? What sleep?

Lily still is not sleeping well at night. Mom and I have been splitting the night so that we can each get some sleep. While she will go to sleep just fine to start the night, after a few hours of sleep she wakes up and then starts a cycle of waking up about once each hour. We are trying a new routine that we hope will break the habit that she has gotten into. We know that how we respond to her cries will affect how she sleeps so we are really looking at what we do when we go in to soothe her. We know that this will eventually pass and she will sleep through the night. We just hope that will come sooner rather than later.
