I've been thinking a lot about this since I'm expecting #2 (a girl) in January. My one brother is 2.5 years older than I am, we were not close growing up, and we're still not close. Because I looked up to him, I thought smart = mathy. My strengths are more verbal, which I translated as "not smart." We didn't fight but we didn't spend much time together either. My family moved frequently and my brother was off in his own world most of the time, so I was very lonely as a child. I'm hoping for a closer relationship between my own boy/girl pair despite a larger gap (39 months) between them.

I'm not sure if this is hijacking the thread, but I'm curious about our generation too, if others got along with their siblings while growing up.
