What's a good reason to give your child a sibling? (Besides having someone to play with) :)

Being a second child, I learned that having siblings make life so much wonderful--and I would not have it any other way. There is so much room for learning--from my eldest sister up to my youngest brother. Having siblings is equivalent to having a lifetime treasure. Having siblings have helped me to solve my problems, be it petty or serious ones. It also helped me become more articulate because of our arguments. Yes, we do argue and fight (a lot), but it's also our way of showing our love for one another. The feeling of being secured is also an advantage if you have siblings. You know you are not alone and you know they got your back--no matter what.
