Dream feeding

Anyone have tips or tricks to successful dream feeding? My little guy wakes up every 3 hours to eat at night but he will only eat a little before falling right back asleep. He definitely does not get a full feed and I can’t keep him Awake long enough to do so. I try changing his diaper between sides or even re swaddling him to wake him but he will just fall right back asleep. Would love to make his night feeds more effective in hopes he can go longer stretches.
