since this is my second go at a crap feeder/sleeper, I can tell you honrstly that it does pass and isn't forever.
I had two bad sleepers too. DS fed two hourly or more til about 6ish months. Then slowly it got less and less. It does slowly get better. It's hard, but it won't be forever. I know it doesn't help much to hear it. People tell me all the time, but its true. You do learn to cope with little sleep. I'm still up 3-6 times a night with one or the other. DS is down to 2-3 bfs a night, at 10mths. DD still wakes a few times a night at 26mths. I cosleep, and DD sleeps in our room too. It does help and I do get more rest (if not sleep). I know how hard it can be.
