I have 3 sisters, and 1 brother. My oldest sister is 13 years older than me, my brother is 11 years older than me, my older sister is 4 and 1/2 years older than me and my sister is 14 months younger than me. My younger sister and I are very close. Growing up everyone thought we were twins because my mother dressed us alike. They treated us like twins too - sort of - we both got presents for each others birthdays and we got identical things for Christmas.

IV4dogs - my husband had a sister two years older than him and a sister 5 years younger than him. We had Amy, Rob two years later and Christy 4 years later. Kind of strange too.
