10 year old asked where babies come from, how much do I tell?

[Rollerboots]

As above, 10 year old son asked, seems genuinely interested.
I asked if anyone was taking about it, he said no, but said he has seen a boy doing a “finger in a hole” motion and want to understand what it means!
Anyone got a recommendation for a book I can read with him?
Any advice welcome!

@Slothlikemum my flight mistake then, I've re googled and seems like most have by 12 and as you say 10% by 9. But 10% could be your child unless they are literally never around devices, or it could be your child's friend who might for example tell your child 'sex is where lots of men strangle a school girl and slap her face with their willies then they squirt stuff on her and she gags' or 'sex is when the plumber comes over and then the mum kisses his willy' etc etc.

So my point still remains that parents should be in control of their children getting correct information about sex as well as knowing that porn is something that they can discusss with them if they have questions and that it doesn't represent the sex that most people have or what people are expected to do when they do have sex

Sorry, been unable to sit and read all the messages until now, wow!
Thanks for all the good advice , I’ll definitely look into some of the books.
He asked late, as he was going to bed, and I didn’t want to start the conversation at 11pm.
He just hasn’t been interested at all so far , I have offered some information at different times when things have come up, and he has absolutely not been interested in learning more, changing the subject to Pokemon!
I’m really open with him so will be more than happy to talk about it all and absolutely want it to be positive chat .
He has had some sex ed at school but so far it’s been about puberty etc and not actual sex .

Not sure if this has already been said but my first instinct is that this kid cleary already knows about sex, likely from school by the sounds of it, but just wants to let his mum know he knows 🤷‍♀️ Or perhaps he does have a bigger sex related question he's worried about and wants to ask and this is his way of introducing the conversation with his mother who clearly has never discussed it with him before.
That to me makes way more sense than him not knowing anything at the age of 10, especially as they start learning this stuff in school way earlier than that.

Not going to complain. To be honest I'm glad she knows. It shows myself and DH have brought her up correct that she came to us and asked us. I then bought her some books that told her more than that tbh. I think the most important thing is she saw the Google results and asked us as she didn't understand. We then told her not to Google stuff in future without talking to us. I had to get my sex Ed from just 17 😄

And her iPad is shut down so it didn't show too much. That's down to the parents I'd say

Depends on the maturity of the child.
By ten they probably know a lot more than they are letting on
