I'm an only child and I pretty much fit the stereotype to a tee: Only-borns Personality Traits Positives: Only-borns are the mega-movers of the world. They are task-orientated; tend to be extremely well organized, highly conscientious and dependable. They are keen on facts, ideas and details and feel extremely comfortable with responsibility. Negatives: The negative characteristics of only-borns can be tough to handle. They are often unforgiving, very demanding, hate to admit they're wrong and usually don't accept criticism well. To others, they seem very sensitive and indeed, their feelings are easily hurt.
I was the oldest. Just had one sister 4.5 years younger. We really weren't that close growing up, but now we are best friends. When I had kids I wanted them close in age so they would have something in common growing up. They're 25 months apart. We want one more, hopefully soon, so Noah, my baby, and the newest edition would be less than 3 years apart.
I'm the youngest of two. But my sister is eleven years older than I am so to a degree it's as though I was an only for a lot of my life. And the dynamic certainly wasn't the "typical" sibling-y dynamic.
