Toddler Milestones...ready for a toddler bed?

Elliott is 19 months old today.  I have watched him reach every milestone right on target, and some he reached early.  I have been told that he is smart and mature for his age.  He is my only child, and I have never spent a lot of time with other children his age, so I can only go with my instinct.

I listen to people complain about their children's habits (not sleeping through the night, etc), but I never had issues with any of this, so it is hard for me to relate.  I did not "ween" him from co-sleeping, the bottle or the pacifier.  Whenever we were ready for a change, we did the cold-turkey method.  I know that does not work for everyone, but it works for us.  He was off the bottle by his 1st birthday.  My own mother said I was mean for doing it that early, but it was very successful, and I do not regret that decision!

However, we have reached a new stage at bedtime.  He knows his bedtime routine.  After he his dressed for bed he brushes his teeth, turns on the CD player (classical music), turns the lights out, and he even points to his bed when he's really tired.  Generally he goes to sleep without putting up a fuss.  The problem is that he is a very active sleeper.  He tends to roll and stretch out so much that an arm or leg somehow manages to slip through the rails, and the next move he makes gets it stuck.  He cries in his sleep because he can't roll over, and at least once or twice a night I have to wiggle a limb back into the bed and reposition his whole body.  I have checked national recall lists, and his crib is not listed anywhere, so that is a relief...but one time his leg had started to swell, and that scared me.

I have discussed this with several people, and they tell me he is not ready for a toddler bed.  However, I have always gone with my gut instinct, and I do not feel comfortable leaving him in his crib anymore.  He is also trying to climb out when he wakes up from his naps.  I don't feel it's safe any longer.

My husband finally agreed, and he converted the crib to a toddler bed last night.  Elliott went to sleep last night without getting out of bed one time!  I know this will not always be the case, as today he got out of bed and played in his room for twenty minutes before I put him back to bed.  He cried for about two minutes (his usual time) and went on to sleep.  I am actually very proud of him.

My question is this...was it too early for this transition?  As I said before, I don't know too many other young children, so I don't know the typical age for doing this.  I know there is not "right" age for anything, but I need a little reassurance here.
