Wake up at midnnight

I thought she can sleep it over whole night already, when I bring her back during weekday night, she still awake every 3 hour at midnight. She sleep besides me right now, so I will alert when she wake up, I know that she definitely will turn left then turn right, and keep on erk ..erk. while she is hungry. Actually sometimes she is not hungry one, she just get used of her drinking schedule drink every 3 hours. So what I am going to do is that I will ignore her first, want to train up her no need to drink at midnight..let her erk..erk for a while, if she cannot tahan sure will cry loudly then I only feed her. But at the moment I am still not success to train her, I heard my friend said that breastfeeding baby is like that one, not sure is true or not.
