I used to think they just come from the mother's belly literary and when शिशु being born, I thought mothers always get cut open, I never knew शिशु come out of the vagina till I was older. When I was very little, I was always confused about the conception ever since I seen Look who's talking movie. I thought the sperm were worms. lol
When I was younger, my mother told me that शिशु were a gift from god, and if he thought आप were worthy, he would give आप a baby, that's what I used to think, until I walked in on the 'making' of my younger sister *.*
I've always known it comes from sexual intercourse. I've never been told to think otherwise and my mother didn't want me nor my brother to grow up sexually confused so she told us where शिशु come from at a young age.
Well, my mom told me I came from Sears, my dad कहा they found me in a potato sack and decided to call me their own, but as I got older I thought up my own theories until one दिन when I was 9 I saw an R-rated movie and, well, I had no need to wonder anymore. ;)
