We dreamfeed our 6 month old at around 10pm every night. This was working up until the 4 month regression mark and since then hasn't been the same.
She wakes up as soon as I go into her room, she huffs and puffs like she's got the hump, knocks the bottle back and then thinks it's playtime when I change her nappy.
I change the nappy as we've had too many early morning wake ups for leaks and more often than not, she's often left a little constipated (reflux milk) nugget in there for a surprise after the feed!
She doesn't sleep through the night so I wouldn't say we feed for that reason, that's just the natural pattern of feeds that works out to be the last feed of the day but that last bottle does see her through until the morning despite her multiple night time wake ups for the dummy.
