In general, bed-sharing is not recommended. Although it's not harmful for your children to sleep with you, it's unnecessary and it may cause problems for you. Children's fears and insecurities can be dealt with in other ways.
Children turn out fine either way.
In some countries, families share beds out of necessity, but most children in our country sleep happily in their own beds. Bed-sharing is not quality time. If your child is asleep in your bed, it is a neutral time. If your child is crying and keeping you awake, it is an aggravating time. Several studies have shown that more than half of the children who sleep with their parents resist going to bed and awaken several times during the night.
