On the other hand, having a sibling allows a preschooler to see the world in a different light. Siblings help children learn how to make friends. They will learn this through experimenting with each other. They may also have an easier time with social interaction and functioning as a member of a group. They will learn not to be frustrated if they re not the center of attention or if they can t always have their way.
Parents can start siblings out on the right foot by introducing the new baby as part of family life.
Keep your same routines and rituals. Also, deal with each child age appropriately. Treat your two year old like a two year old. Don t expect him to act older because he s not the baby anymore. You can also expect the older child to regress somewhat in an effort to be treated like the younger sibling.
