When my twins were about a year old I was exhausted from constantly feeding overnight (each twin 2 or 3 times a night and they never woke at the same time) so I started offering water in the night instead of a breastfeed. It worked in that they no longer woke for a feed, I guess water was not as appetising for them to want to wake up for. Just another suggestion to add to your arsenal as you get her to sleep a bit more at night
