Having a baby is an important event in your family. But after your first child is born, your excitement over the next pregnancy may not be shared by everyone. Your first-born child may feel a little anxious over their future little brother or sister. If these feelings are not confronted and discussed, your child's feelings of anxiety could easily turn to feelings of resentment.
Older children have many reasons for worrying about a new baby.
Usually they feel that they will be pushed aside or ignored. They are afraid that they won't be needed or wanted any longer once the new baby arrives. They see how everyone around them is excited about the new baby and feel left out. Maybe it seems to them that the new baby is always the main topic of discussion. Siblings that become insecure of the new baby can act out in several ways.
