My DD is 11 months old and ( if we discount the first 2-3 months when the sleeping pattern was still erratic because of night feeding) we have only had 2 sleepless nights (when teething) in 8 months. I think it's quite special!
Everyone says how lucky we are and she and her big sister have the same bedtime from about 8.30 to 8.
I am saying as a positive example and my intention is not to "brag" about it I just wanted to share
