I was an only child until I was 5 when my sibling was born.
My twin sister and I had seven years before my brother was born.  
Cool, siblings can be like really good friends if they get along. I'd say me and my sister get along pretty well.
Going from an only child to having a sister must have been an adjustment.
Yeah but I am grateful for my family now. Only children are pretty uncommon and have been throughout history.
Interesting, I suppose that makes sense.  Larger families were probably the norm for a long time and before birth control.
It has even been such a problem that China instituted a one child policy from 1979 to 2015.
