I don't quite dream feed, but we wake him up slowly at 10.30, change the nappy (otherwise he'll be soaking in the morning) feed him and more often than not he's fallen back asleep before he's finished the bottle. I tried to skip this feed a few weeks back and he was up at 2am and then disturbed for the rest of the night. Well worth a few goes!
Funnily enough he's usually a bit pukey/windy, but if he's fallen back to sleep on the bottle he doesn't need a wind and can go straight down with no problems. If he's still awake then I will just give him a quick wind and back down.
