Getting the oldest to sleep

It's pretty ironic that the baby sleeps through most of the night, maybe wakes up once, and our older son is the one waking up repeatedly.  I know it is because he is in his "Big Bed" and I know he is probably a little young to be in the bed, but we worked him into it so the crib will be available when we move the baby into his own room.  We read Berenstein Bears' The New Baby for weeks.  The story is all about Brother getting a bigger bed.  At the end of the book we would give our son the choice to sleep in his little bed or his big bed.  For awhile he wanted his little bed, but then one night he decided he wanted to try his "Big Bed."  He wanted mama to lay with him the first few nights and I quickly moved to the floor so he didn't get used to needing me in his bed to fall asleep.  I have since been able to get myself out the door with my head near the doorway to be near him while he falls asleep.  The problem is that he wakes 3-5 times or more a night.  My husband has been the one to help get him back to bed/asleep since I need to be available to feed the baby if he wakes.  However, my husband falls asleep on the floor for hours and his snoring along with Cael's restlessness can wake him up again.  He started to lay on the floor by daddy, which translated the other night to having to lay on the floor by mommy to initially fall asleep.  And again in the middle of the night to fall asleep again- I think he partly thinks it's fun to sleep on the floor by us.  However I again don't want to have him rely on lying by us to fall asleep.  So last night began our journey to get him to at least sleep in his bed. 

He fought going to sleep in his bed by throwing a fit and kicking the bed rails.  I looked into his eyes and told him that wasn't ok and that it was time to sleep.  I reassured him that mommy was sitting right by the door.  He fell asleep quickly after that.  However he woke every hour or 2 and tried to fight the fact he needed to sleep in his bed each time we went in.  My husband did well with it.  We made the plan to reward him in the morning if he was able to at least sleep in his bed.  Our goal was to try to console him before he made his way out of bed by letting him know daddy was there.  He did manage to get out of his room a couple times before my husband heard him, but my husband stuck to the plan very well and managed to get Cael to fall back asleep in his bed.  It got more difficult as the night went on, and eventually he wanted mommy, so I helped out.  In the morning we rewarded him with a cookie for sleeping in his bed and really made a big deal about how well he did even though he didn't like it.  Our plan is to reward him with some small cars and spread out the number of times he needs to sleep in his bed and he gets more used to the idea.  We just have to get some cars, so in the meantime- cookies it is.  This will be a definite trial and error process, but I'm hoping to get him sleeping in his bed before he gets too used to getting up all the time and falling asleep on the floor by mom and dad.  To be continued!!
