Hello,
My LO had never done a dream feed. I found that her stretch of sleep earlier on was usually after first going to bed, like you are describing. For us, it was about 3.5 - 4 months when she stopped night feeding at night (I don't know if this is the average time or not). She is bf and I noticed her seeming to get less interested in the night feeds. She wasn't going on for very long, and not taking nearly as much as she did at her other feeds during the day. What I did then was reduce the amount of time I breastfed by a minute every few days until it was gone.
However, like Ellen's LO, my DD also resumed a night feed at about 6 months. I tried everything else to settle her but nothing would, and she was hungry. I think it was related to her 6 month growth spurt, but it did continue on. In total, it lasted about 4 weeks. Like before, I noticed her scaling it back herself a bit so I did the same thing and reduced the time I fed her by one minute every few days. This time, she actually dropped it herself when we got to 4 mins. It's still very fresh, but she's been without a night feed again now for just over a week. Fingers crossed. I am now able to settle her without a feed if she does wake. Doing it slowly like this allows your LO an opportunity to make up for it by increasing intake during the day. With bottle feeding, I have seen posts where people slowly reduced the amount by an ounce every few days or used increasingly watered down formula.
