how can i stop my baby's mid night feeds?? she cries and just doesnt take top milk..

My son is 6+ months, and is still waking up for night feeds but however when my daughter was about his age, she never wakes up for her night feeds and I remembered clearly the only times she woke up was because of a high fever. I've tried what Hui Qun has suggested, but sometimes baby is just hungry like my son. He knows it's night time, he knows that it's time to sleep but milk is a must. What I do is prepare warm water in a flask, 3 canisters of milk powder and 3 empty bottles and placed them next to me. If he wakes up, it takes less than 3 minutes to prepare his milk and I get to dream feed him which means max 15 mins. It's not too bad for me, I still get to sleep and wake up early for work the next day.
