I agree with Arcadia - nothing works without support. If you are in that situation it wouldn't matter what you did, you would still reach a point where you just burn out. And there are no guarantees that if you followed other methods that you would have babies that slept better. Some babies are just crap sleepers period. I know what it's like to feel like you are mostly doing it alone too. When I had our 3rd bub DH was working a 13 day fortnight with only Sundays off and 14 hour days for SEVEN MONTHS!! I had a 3.3yo, a not quite 2yo and a newborn and it was hell! It was the hardest thing I have ever had to do. So I totally understand where you are coming from in that regard. So just do what you have to do and when you do have the support available to you grab it with both hands and take it. And don't be afraid to tell people you need help. We get pretty good at making it look like we are coping and have our act together when really we are like a duck on water - calm as anything above the water but paddling furiously beneath it.
