Hello and welcome to Mothering!
We have a forum on Co-sleeping and the family bed. Some of the people there may have some suggestions for you for bed weaning. http://www.mothering.com/community/f/37/co-sleeping-and-the-family-bed
Also, there is the Toddler forum. http://www.mothering.com/community/f/31/life-with-a-toddler
Best wishes to you--I find this age difficult for sleeping.
