Controversy over the family bed, or co-sleeping as it's often called, seems to come and go in waves. Currently, most child development experts, even those who were previously opposed to co-sleeping, take a middle-ground position on a family-that-sleeps-together policy. Most now admit that an issue this personal has to be decided by you, taking your own family's needs and cultural background into consideration. Be sure that you're making an informed decision, so you know what you're getting into if you let your child begin -- or continue -- to share your bed. Feelings run high on both sides of this intimate issue.
