We Have A Problem!!!

Help me please! I have not had any sleep, and I feel like I'm dying. Grant did so well in his big boy bed for a few nights, and this week has just gotten progressively worse. I thought it would get better, but after last night I'm ready to throw the big boy bed out the window, make his room into a toy room, and just let him sleep with us. Seriously, I've had maybe a total of 4 hours of sleep, and I just don't know what to do. I'm pregnant, and this is not making this any easier! I know this problem is all my fault because I didn't let him cry it out when he was 10 months old and started waking up screaming every night, right?! Well, easier said than done. When he was 10 months old, I was (and still am) working full time, and my job required that I be coherent 8 hours per day, and I couldn't do that if I had to listen to my baby cry for 2-3 hours per night. Now, I don't have to be quite as coherent, but I do have to shower and come sit in a chair all day, so sleep really helps.

Last night was a disaster...
I laid down with Grant around 9:00. I don't know what time he feel asleep because I probably fell asleep first. I woke up around 10:30 and wondered to my own bed. Around 1:30ish, Grant woke up yelling for me. Pookie tried to go lay with him because I didn't even hear him yelling (even with a monitor, does this tell you how tired I am??!). Anyway, Daddy just doesn't do the trick. Could it be because his hair is very short? He kept yelling, "mommy, where are you?" At that point, I went into his room and laid back down with him. He said, "I need your hair." I think he has an obsession. It all started a long long time ago, but now, he needs to touch my hair to go to sleep, ughh! Anyway, I waited till he went back to sleep, crept back to bed, and laid down. I, of course, have to the bathroom every time I wake up now, and after all of that it took me awhile to start dozing off. No need to doze, as soon as I did, Grant's at it again. This continued for most of the night. Then, I finally gave in and brought him to our bed, but guess what... this isn't what he wanted! He started crying to go to his bed!! When we got there, he patted the pillow next to him and said, "mommy, you lay right here." Over and over. Finally, I laid him down crying, and went back to my bed. He continued to cry so I went back in his room after awhile and told him he could come to bed with me or lay in his room alone. He chose going to my room where he began to cry for milk! What's up with this? I haven't ever given him milk in the middle of the night, not since he was like 10 weeks old and still nursing! He finally went back to sleep even though I pulled my hair back and refused to let him touch it. He reaches for it in his sleep! So, even though he was asleep, I was trying to avoid his little hands for the remainder of the night and he even woke up crying 3 more times for who knows what. By then, the alarm clock was going off!

I hope that he's not getting sick or anything, but I really hope last night will never happen again. I don't think I can handle it. I need advice, PLEASE!! What do I do? He has nothing that he feels like he needs to go to sleep, no blanket, pacifier, animal, etc... all he wants is my hair, and I'm withholding that! I've tried to give him something for security, but he tosses them all aside. So, if you have suggestions, please leave a comment! I don't care if I know you or not. I'm willing to try just about anything!
