Talk to him-- see what questions he has. My daughter is 8 and is so physically developed she looks like shes 13! So I watch her being around older kids because they dont realize how young she is.. But I do ask her if she has any questions, I am light I dont talk about what sex is really but I do talk about good touch and bad touching etc.

my boyfriend has two older boys and I have a 11 yr old daughter so he is around older kids, plus dont forget the bus and playground. even the second graders talk. things have changed so much from when i was in school.

what I have learnt, is just answer the questions they ask. Don't elaborate. She may come to you later and ask but just give them the facts as she asked for them. Put yourself on her level of understanding and language. I actually used to enjoy explaining this to my girls it was the bnoys I used to say GO ASK YOUR DAD!!

my daughter is 7 and has been asking for the past 2 years about babies and how they got in and how they gat out lol. I told her that firstly you need a mummy and a daddy to have a baby and mummys have tiny eggs in there tummys which grow into babies when the mummy and daddy love each other enough. also just told her that babies come out your tummy but she got told by someone in her class where they come out lol x

I am pregnant right now with our 3rd child. I explained to my daughter about eggs (I didnt tell her about sperm) and how the baby grows. I'm not sure what to tell her......or you! I think it all depends on the childs maturity level. Good luck!

My daughter and I watch a show on DISH network called Deliver me. You don't see the actuall way the baby is born but I feel she understands. This show takes the whole nine months in an hour. Sometimes a c-section sometimes a vbac, she isn't the least bit grossed out and I think they do a great job. We have talked about the babies being born in the tub and pool and then the one she had her baby in the toilet she kept saying (the woman) I feel like pushing, my daughter said get off the pot or the baby will fall in the water. Just matter of factly . So she knows but hasn't ask how they got there yet.

My son is 7 also and I've heard that that's the recommended age for the talk these days. I first told my son that I held him in my belly for nine months... Then one day he wanted to see the scar where the baby came out and I told him that that's not how it happened and he wanted to know so I just said he came through my vagina. He asked what a vagina was and I told him it was mommy's pee thing. Then he started talking about having babies himself and I corrected him, then he wanted to k ow how the baby gets there in the first place so I said, at first, that mommy and daddy came together in a special grown-up way and the baby started growing...After a while that no longer sufficed and he wanted more info. Eventually I told him about semen and egg and itwas uncomfortable. He's so young. But when I explain things in scientific terms it feels more appropriate. He seems to have no opinion-just curious. I agree that it's best to satisfy the questions and not elaborate. It took my son about a year to get that much out of me. I still don't think he has the full picture yet but as time goes on he'll collect all the puzzle pieces and put them together. Don't be afraid to answer the questions. It's better they hear the truth from us than learn about it playing spin-the-bottle when they're 12.

I had the talk with my son when he was 7. He kept asking questions so I sat down and was very frank with him.

He already knew that the mom carries the baby for 9 months and it comes out of the vagina or by c-section. He was asking how the baby got there in the first place. I told him very clinically about sex and how it works.

He kind of made a funny face and said "really?" I wasn't sure that he got it completely, but then a few months later, he found out that a friend of his was going to be a big brother. He asked me if his parents "did that thing with the penis and vagina." I said yes. He definitely gets it.

I'd much rather my child find these things out from me that from his friends. And believe me, kids talk...even at age 7.

I don't know how you have talked to your son up to this point, but I have always been honest with my kids.
From the time they were babies I told them that their penis was a penis. When they got older and asked if girls have a penis I told them no, girls have a urethra for going pee and a vagina that makes us a girls. Basically they stuck with boys have a penis and girls have a vagina. (now that they are older they are less comfortable with the V word!)
When they were in preschool they learned about the birds... literally! they were told birds have eggs which form babies when the daddy plants a seed in the egg. The teacher elaborated that people come from an egg and a seed too. This was enough for them. They told me the facts and had no questions about it.
I am pregnant now and have asked my son how we got the baby. He told me daddy planted a seed in my egg. I asked him if he knows how the baby gets out. He told me they cut it out. I explained that mommy's have a special place for babies to come from which is between legs and seperate from where we poo and pee. I told him that when the time comes I will have pain as my body gets ready for this and asked him if he had any questions, but he didn't.

My son will be 7 in May. I think at this age giving too much information just leads to confusion and giving too little leads to a lack of trust.
My son asked me once what a prostitute was because he heard it on TV and I told him it was a person who takes money from people who want to touch their body in a not good way. Too much information there would have led us down a road we don't need to go down! LOL Each kid is different, so let your son be the lead.
I think your best bet is to try to monitor as many conversations as you can and ask him if he understand what the other kids are talking about. Clarify if you need to, go over good touch vs bad touch, and let him know there are some topics he shouldn't be talking about because he is a kid and kids should talk about kid stuff!
It won't hurt to remind the older siblings that they need to watch what they talk about.... my older son is 12 and knows that there are inappropriate things to discuss around his little brother. I remind my nieces and nephews also. But my 12 year old is just getting to the point where he needs to know stuff and wants to know other stuff. It's okay for kids to be innocent and not know too much.
