I, too am an only child, both my parents are only children, and I have one child. Crazy! I know! The truth is, neither my grandmother, my mother, nor myself planned to have only one child, but we happily played the cards fate dealt us. In my case, I truly wanted more children. I always envisioned myself with three rambunctious boys, but I ended up with one lovely daughter.
As an only child myself, I can honestly say that I have never wished I had a sibling. The hardest part about being an only child for me was feeling a tremendous amount of pressure to succeed - sort of like the "all eggs in one basket" scenario. But the wonderful thing is that I am extremely close to both my parents. They even moved twice- once in college and then again after my daughter was born, to be closer to me. I always felt very privileged, but looking back I realize that we weren't financially better off than my friends, but because there was only one of me - we could afford to do more. Think of all the expenses that incur over time... clothing, sports, family vacations, braces, glasses, tutoring - and later cars, insurance, class trips, college tuition, fraternities - the list is endless. With one child, it isn't quite as daunting.
My husband and I tried for many years to have a second child, but now my daughter is 11 and while at this point - once we got over the shock, we would certainly welcome another child - we are no longer trying to conceive. I must admit, I really love the life we have built, and the freedom that having only one child allows us - especially now that she has gotten a bit older. When it comes to her activities, unlike most families who are scrambling to get all the kids to soccer and dance class and piano and baseball, we never have to "divide and conquer." My husband and I can be at every single game, every single recital etc. because we never have to choose. We have a lot more time as a couple than most parents I know, because our daughter spends the night out at friends' houses - so we can have date night without hiring a sitter, or we can simply stay in and watch a movie - a luxury that our friends never have. Our daughter's friends have even commented that they love to come to our house because she doesn't have any brothers and sisters, and they have everything to themselves. Also, we have the luxury of being able to travel more - both with our daughter and without. One extra plane ticket is do-able for us, but two or three or four??? Definitely not. Often when the three of us are out to dinner I will see a large family at a table nearby and I'll wonnder to myself, "how can they afford it?" I consider it a true privilege that I've been able to stay home with our daughter - although had we had more children, I'm not sure that staying home would be an option. So maybe things happen for a reason.
On the flip side, I do sometimes look longingly at my friend with her four children - not so much because of the choas she has today, but because of the many years of big family holidays and multiple grandchildren she'll someday enjoy. She has FOUR children who think she is the prettiest, smartest, most wonderful woman in the world. How cool is that? And I have one - and one is a miaracle in itself.
