The remedy for this is simple, yet difficult to execute. Bottom line, at this age, night time is for sleep. She's old enough that she doesn't need a mid night feeding. She's also old enough that she needs to learn that there's no mid night parties at her "crib"!
One of my daughters pulled this after sleeping beautifully for months, and my very protective cat resolved it by getting in her crib and keeping her company. Apparently she just needed the reassurance that she wasn't alone.
What you need to do, is to stop the feeding during the night. When she wakes up, simply lay her back down - without taking her out of the crib!! be quietly cheery and reassuring, and leave the room. give her 5 minutes, and if she's crying, repeat the process. do NOT lift her out of the crib. After a couple times of this, just peek your head in, smile, tell her it's ok, go back to sleep, and leave (hide).
This could take a few nights, but she'll get the idea that nighttime is not playtime or cuddle time or eating time, it's sleep time. It's a rough process, went through it with my 3 girls. Once you get through a couple nights, you'll be well rested!
