A toddler who becomes accustomed to bedding down with mother and father has been known to refuse sleep when placed in his own bed or crib. This may also interfere with naptimes. The message is clear that if you are going to co-sleep with an infant, introduce the baby to his crib by 6 months of age. Another frustration that occurs in the family bed is the most obvious one. The parents sex life is adversely affected.
Spontaneity becomes almost non-existent.
This could pose discomfort to both parents, as most children are quite active in their sleep. In many cases, one parent retreats to the sofa. Conversely, some parents find that sleeping with their children gives the child security and they inevitably sleep better. The family bed is a personal decision. Sleeping arrangements should be comfortable for all involved.
