Let your child ask any questions she might have about the baby and about raising a baby. Answer the questions honestly. Let the entire child rearing process be educational. You may even want to encourage questions by your child. Ask if she has any questions about the new baby.
Open discussions are always key.
As your children get older, let them play with each other and work out any differences on their own. They can grow close and begin a lifelong friendship. You ll want to supervise as much as you can. But your children in their early years will learn a lot about life from just being around each other and working out their differences. Learn how to harvest a healthy relationship between brothers and sisters.
