We have tried everything ????

He has not been a good sleeper since he was born. In 9 months the longest sleep he has had was 6 hours (it was great, we actually slept too).  He will not go near his crib, not even for a nap. A couple months ago we tried to get him used to sleeping in his crib, so we did the put him down in the crib he slept for 20 minutes then started to cry, I (the father) went into the room and layed him back down gave him the soother back, didn't speak or turn the light on and he just stood back up at the edge of the crib and screamed. I let him cry for about 5 minutes and went back in layed him down and gave him the soother again. He stood back up and started screaming again. We let him cry for another 5 to 10 minutes and went back in and tried this a couple more times and it didn't work. So we removed our box spring and put our mattress on the floor, and put a foam mattress beside our bed on the floor because now when he sees his crib he gets fussy and  starts to lightly cry. He sleeps in our room on the foam, he is still breast feeding and the only thing that will calm him down every hour is breast. He wants nothing to do with me (the father) when it is evening or night time, and my wife can not function anymore. She is up every hour,  and I am a very light sleeper so I am up every hour too. We have tried Similac before bed and it worked for a week, he slept for about 3 hours then woke up needed breast and then went back to sleep. He isn't drinking breast milk at night he just needs the comfort of it in his mouth and then falls back to sleep. Now the formula doesn't help anymore he won't take it. It is like he doesn't like it anymore. We are putting him to sleep at the same time (roughly) every night, trying to find him a routine. He naps twice during the day, on a good day the naps are and hour, not a good day the naps are 20 minute power naps. He is not gassy, he is teething but the nights he wakes up because of teeth it is a different cry and we put oragel on his gums and give him a holistic natural pill and it helps and he goes back to sleep. It is not teething every night. We spoke to our Dr. and he says to keep trying the crib thing and let him cry, but he fight us when we even go near the crib, he pushes away and starts wining. I can't force him to go near the crib, it is not right. I am reading a book on infants sleeping (i don't remember which book) and it says the same thing as what we have tried.

Any suggestions would be greatly appreciated.
