Wanted: A Good Night's Sleep!

I don't know if you would say I am venting, looking for advice, or raising a prayer request, but last night marks the 34th night my husband and I have gone without sleep.  Our 21 month old decided the day I went back to work for the school year, he wouldn't sleep.  We thought at first it was just new adjustments, but after one week we still were up most of the night.  When then quickly discovered that he didn't like his crib anymore, and since he has pretty much done everything early( walking, talking, etc.) we figured that made since.  This weekend we had the bright idea to change his crib into a toddler bed.  We even let him pick out his "Diego" bedding.  The first night when it was time for bed everything went as planned.  He went to bed and fell right to sleep.  My husband said,"This is the night, Babe!" We went to bed with high hopes, only to be disappointed again.  Every night since, we have been woke up at least 6 times, because now he can get out of the bed and come and get us.  I don't know which is worse, the constant wailing, or the little tap in the middle of the night.  We are pretty much at our wits end.  Today we decided to convert his crib into a double bed, so that we can at least sleep with him if necessary.( I am sure that is what its going to come to) To sum it all up, I am praying for a good night's rest!  Any suggestions are very welcome!
