can i tell you what i did with rosie at 8 weeks re dream feeds?
what i did was express into a bottle as much as i could throughout the day. then at 10pm i would wake rosie fully (not the point of a dreamfeed but we'll get there in a minute!). I'd breastfeed her until she seemed to stop and then i'd offer her the bottle, which she'd take more milk from. when she was really turnign away and definitely still awake (i wouldn't let her fall back asleep) then i put her down to sleep.
when she then woke up 3 hours later i gave her a paci (we've weaned off it now by 6 months so it's not a scary or bad thing to do!) and she went back to sleep. it was clear her waking was suck related not food related.
she'd then wake up at 4 am and i fed her again.
after a few days of this she stopped doing the first wakeup and so i started to offer the paci at the second. of course if she'd been unsettled i'd have fed her, but she wasn't she would go back to sleep.
it took about a week and suddenly she was taking 2 full breasts plus a couple of expressed ounces at 10-10.30pm and sleeping until 6 am! bliss!
after another week i tried just offering the breasts and not expressed milk as well (I think a week of expressing made the milk production increase so it worked out the same). and then after a few more days she didn't even wake up for the feed.
since then she's been picked up for a dreamfeed at 10.30 (oops got to go do that in a few minutes then!) and not woken until 6 (few blips though around weaning time, and when she's not been well but otherwise brilliant).
so i suppose the point is, dreamfeeds can work to ge tthem sleeping through the night, but you need a strategy to drop off the middle of the night feeds. simply giving a dreamfeed isn't always enough, if the other feeds are a habit then maybe you need to try and tackle that and see if your baby can do without them.
It worked for rosie, and another baby belonging to a friend, but i have another friend whose baby is now 5 months old and still needs at least one nightfeed. which is fine, it's just some babies can go all the way through pretty quickly. you won't know unless you try though!
