Hey S.,
Wow, your story sounds so similar to what we are going through with our almost 8 month old. We also have an almost 5 year old . We had the same story with him except we did the co-sleeping (tossing,turning,waking etc.)the first time and learned to try a different approach the second time. Well it seems that some children are just better sleepers than others, and we didn't get that kind. I have been given the same advice as lots of your responces and read piles of books that praise the cry it out method. This method works for most folks but not all can do it. I do not feel comfortable letting my child scream himself to near hyperventalation for the sake of some small amount of sleep. My best advice to you is to make peace with your little insomniac and know that it like childhood, won't last forever. I wish I had a miracle solution for both our families and if you find one, PLEASE pass it on. It also sounds like you do most of the nighttime duty on your own too. Try on a day when your husband isn't working and ask him to do one night of feedings so you can get a little sleep for yourself. It's amazing what 5 hours of sleep in a row will do. My only other thought is that maybe you have an option that we do not, a well rested family member that might do night duty once in a while.
Dreams of sleep,

PS For crazy screaming fits(by the baby)I have given him the Hylands teething tablets and they really help calm him and relax him into a gentle sleep.
