Make sure she's on a pretty regular routine, getting plenty of activity during the day & getting a full tummy a little while before bedtime. Depending on what she wakes up in the middle of the night for, there are some other things you can do. If she's hungry, you might still need to feed her... if she's just wanting to be cuddled, cut down on cuddle time a little bit. My son randomly started sleeping ALL night right before he turned 10 months, so maybe your DD will start sleeping more soon.
