need advice on moving up bedtime

lchitt

I start back to work Monday and right now although she sleeps she will not go down until btw 11 and 12 every night. She will sleep exactly 5 hours then bottle and right back down in 20 minutes for another 3 hours plus. Waking at exactly 8 every morning. I have tried doing bedtime routine at 6 7 and 8 but no matter when i start it it is always around 11 or later before I can get her to go to sleep.  Do you have suggestions? or do you think when she is forced to rise at 630 she will change her clock herself?
