I'm currently having the exact same problem and I'm at the end of my tether knowing what to do, I've pretty much come to the conclusion that I'm just going to have to ride it out! My 3.5 month old son has been a great nightsleeper from 2 weeks, settled himself to a bedtime of 7.30am with 2 feeds, dropped the 1am one at 6 weeks.
But at 12 weeks this all changed, coinciding with growth spurt and innoculations. He now wakes every 3 hours ish, and won't be settled without BF. He has never had a dummy and I don't want to introduce one.
I decided that his rubbish daytime sleeping must be the issue so I am on day 9 of sleep training and it's going really well, using a shush/pat type technique. Not sure if I'm brave enough for it at night though!
I read on another thread that it's a good idea to take them off the breast once the sucking gets less strong, to try and make sure they don't get in to the habit of taking lots of calories at night.
Would moving towards a 4 hour EASY help?
I am completely exhausted, haven't had more than 2 hours sleep at a stretch for 3 weeks now. Plus the sleep training is very labour intensive, and has been a bit hard on the ears/nerves at times.
Who took my fabulous night sleeper and gave me this rubbish one?!!!
