I am an only child and grew up seeing my cousins only on weekends. I have a 2 year old boy and will be having a girl in August. It is starting to become more real that soon I will need to learn to deal with the challenge of sibling rivalry, jealousy, and other conflicts I never had growing up. How did you manage to deal with sibling bonds and rivalries being unfamiliar with it growing up?
