Most of my siblings got married and had children, in that order. So when our 17 year old younger sister got pregnant, we had a lot of explaining to do to our 6 year old niece. "How come she still lives with Nana but she is going to have a baby? She's supposed to have her own house!" "How come she isn't married? You said when two people fall in love and get married then they have babies. She's not married." "Isn't she too young to have a baby?" Oh dear.... My daughter is only 6 months so I don't have to worry yet. But I'm not looking forward to those tough questions.
