Dream Feeding

Looking for some advise on dream feeding. My LO is 6 weeks and I have tried dream feeding the last few nights with no change. She normally would go to bed at 9ish after a feeding, then wake up around 2-3am for next feeding. This week, I tried adding another 11-11:30pm feeding to get a little longer sleep time. However, she still wakes up at the 2-3am time. Any advise? (I'm thinking maybe she's just too young to expect consistent results?)
