Hi C.,
Boy, can I empathize with you. I have been thru the same situation but for different reasons. I think the birth of my second child set off my first one. When my child was 3 1/2, I gave birth to my second child. All of a sudden, my first child would not sleep alone. Even though we never ever shared a bed with her. I didn't believe in it w/first child. This may not seem so bad but I had an 3 week old infant in my bed (going thru a growth spurt) that was up every hour and my 3 year old up every 2 hours. Not really getting any sleep but was losing my mind. I had it one day. I called the parent hotline, I called the pediatrician, I called a child sychologist, her grandmother, my boss. I called everybody I could think of. Here is the solution we came up with......
We allowed her to take her sleeping bag and place it on the floor next to our bed. Each night she must move the sleeping bag closer to her room or bed. She decides how much to move her sleeping bag. It could be close to nothing or it could go 1/2 way across the room. That was her choice. Granted this was not a over night fix, but it put her in control of her own feelings. Each night, she would move the bag but still wake up every 2 hours to make sure we were ok. This eased up with time and patience. Something I'm not very good at when I'm over tired. She eventually made it in her own room, in her own bed. I have always laid down with my children briefly when I put them into bed. We say our prayers, then I wind up a music box. When the music stops, I get to leave the room. This way I never got stuck with having too lay with my child until they fell asleep. It was really just a way to limit bed time rituals. We also put a sticker on her calendar every night she moved her sleeping bag closer to her room. Once she was sleeping in her own room we started over w/special stickers. Each night when she slept in her own bed all night with out any setbacks or interruptions. On would go the "special stickers". Once we had 14 days in a row w/special stickers, then she got a prize. We talked about what the PRIZE would be before we started the whole adventure. Remember that it takes 14 days in a row to change a habit. If on day 10 he is not feeling well and you let him back in the bed, then the special stickers have to start all over again. I hope this gives you a little more support. It can change but you have to be consistant! Routine, routine, routine!!!!! I did not believe in routines until I had children. Now, god help me if I skip 1 step in the routine, My children are 9 & 12, they still expect the routine. Which is kind of nice, my almost teen doesn't like to spend time w/ mom any more. So, it has become our bonding time.
I also wanted to let you know that my second born still suffers from reflux, gerd (what ever you want to call it) even to this day. She has been diagnosed with asthma, this is a side effect of the reflux. As the acids move up the throat, it irritates the lining of our lungs also, therefor causing asthma. I have alot of experience w/ her and gerd, she has suffered over 9 years with it. Soon we will have her esophagial lining scoped to make sure no damage has been done thus far. Just wondering if he has been to a gastroenterologist and what meds is he taking? How was he diagnosed w/reflux? If you want to talk, just email me a personal note.
Hang in there! This phase may seem like it will last forever. Then comes the next phase and we start all over again. Welcome to all the joys and setbacks as parents.
THe other thing you may want to try is let your son know that in 3 months when he turns 2 years old and you have his birthday party, he will be a big boy and will sleep in his own bed. If you mention this phrase at least 1x/day or 4-5 x's week. Don't make it sound threatening. Just matter of fact. I did this to wean my second child. This also worked wonders.
She did ask twice after her party but excepted the answer "remember our deal big girl". You could even both pick out new sheets for the bed of his own. Something special for the big boy who will be sleeping in his own bed.
Also I don't know how long your hair is. Have you considered flipping your head upside down and clippping a piece big enough that he could hold thruout the night? Just a quick thought.
