What age do you start talking to your kids about reproduction?

[MarshmallowAra]

Not really an AIBU, I know.

Two wood pigeons have just bred while i was watching them out the window with my DD who's almost 4.

I usually try to explain things to my child in an honest, factual way. But is it too early to try to introduce the basics of reproduction (and will other parents be really pissed off if she repeats anything to other kids)?

@Camomila 1 in 5 U.K. babies don’t come out of a vagina you know 😉

Yeah we didnt go down the route of babies coming out of vaginas either because although DS did, his little sister did not!
