How is it that little bitty toddlers can take up the whole bed?! I am still trying to figure that one out w/ my 17 month old... He sleeps in the crib most nights all through, but he is teething... Teeth are terrible things aren't they!? lol. Anyway, before you try, be sure you are not weaning him off anything and no teeth are coming through and he isn't sick. I think also if he is clingy, then at this stage, being 14 months may not be a good idea for a transition... You can try. I am sitting in my boys' room waiting for my youngest to go to sleep right now because I refuse and think it is cruel to let him "cry it out" (Ferber actually said that what we call the Ferber method is not what he meant at all!)
We started by putting him in the crib during the day to play so it isn't a scary unfamiluar place. Then start putting him in when he is close to sleep, after of course a bedtime routine of sorts, you may have to stand there and rock him back and forth. Keep doing it until he stays asleep.
Next step is a while later, when he is more used to it, put him in the crib at night after getting ready for bed. Sing, or put music on. My babe likes a light up aquarium thingy for the crib, and his Scout Pal Dog (a leap frog toy). He now thinks he needs to get up to start the aquarium when it stops! LOL
Then do what I am doing now, sit and let him go to sleep. You can sing, pat his back, hold his hand. Whatever helps. The next step... Well, I need to get there! LOL! Hang tight, before he is 18 years old you should not have to have hime hogging the bed!
