How to talk about the birds and the bees?

My eldest son is almost 8, I haven't had the talk with him yet, I like to be open with my kids, he has never asked, he did recently ask me if the Easter Bunny is real and I told him the truth, he took it really well. He has seen me pregnant and breastfeeding, his dad and I are still together, My parents are divorced which has confused him sometimes. Anyway, I have told him he will get body hair one day and he knows where babies come out and he knows I had csection. I am unsure how to bring up the topic and what to say. I had him when I was 15 and got married a few years later so I need to be prepared for any questions.Please do give me suggestions, how do I bring it up? via /r/Parenting http://ift.tt/2dB5k86
