DD used to go to bed at 6.30 but when she hit 10 months that went out the window! So now her bed time ranges from between 8.30 - 9.30 and its working for us. If I try to get her to go to sleep she just gest upset and I get upset so I just leave it now. If she is showing sleepy signs then I will do the 15 on 15 off rule and some times it works sometimes not - if she isnt busy then she just has a play with her toys while we do stuff or we read her some books. I just go with her flow now.
