i had this problem with my daughter a while back. she is 13 1/2 months now.
i would do the bedtime routine, then instead of rocking her to sleep i would put her in the crib and rub her back. after that started working i would do it less and less and just sit by her crib without touching her until she settled down and went to sleep. then i started leaving before she was fully asleep, staying a little less and less each time. but if she cried i would come back and sit by her crib but not touch her. now, i can put her in her crib wide awake after her bedtime ritual of washing up, kissing daddy and her teddies good night and reading a story, and she goes right to sleep. occasionally she will cry a little but i can go in and hug her and tell her go to sleep now and she will.
this took weeks and weeks to do but i didn't have the heart to just let her cry every time so i just did it my way. anyway, hope something here helps you. good luck!
