this is what Spock use to do. fortuantly it is rare these days to have the hr long sessions. Spock still wakes every 2-3 hrs, sometimes she will squeal in her sleep and ill gobto resettle her but she is still asleep. I notice if she is in pain/discomfort that is stopping her sleep (you can tell she is tired and trying to sleep but its stopping her) I burb her. like I did when she was a little baby, put her over my shoulder and pat her on the back. Sometimes she burbs, sometimes she farts. and then she is happy.

don't know if this helps, but Spock is now 12 1/2 months and has only really gotten better in the last couple of weeks. so was doinfg simular to miss G at her age.
