How can i expect my children to react when i tell them i am pregnant?

Unexpectedly: Every child may react differently depending on birth order, age and temperament. Teens and preteens may be embarrassed that you are having sex and their friends will know it. Very young children won't understand. Reactions can range from happy excitement to anger. Whatever their initial reaction, it's likely to change with time.

Depends: Depends on their ages and your family dynamics.
