4:00 am wake up call

So another piece of information that you may not know about my little E is that every morning at 4 am she wakes up and comes into my bed.  I know your thinking "she's two years old why is she waking up still?".  Well thank you to the lovely transition from a crib to a BIG GIRL BED.  For the past two months she gets up in the night.  I really don't know how to break this habit or I would have tried already.  The sad part is my body is actually used to this routine.  I wish I knew what it felt like to sleep through the night again!

Help! Any ideas on how to get her to sleep through the night and stay in her own bed??
