DS is 6. I've always said I will just talk to my children about sex in an age appropriate manner and not let it be a 'thing' but I failed at this 
So twice recently DS (age 6, year 1) has asked where do babies come from. And I basically fudged it and distracted him - I'm not impressed with myself and want to rectify. Thing is I'm just not sure what to say to him? What is age appropriate for 6? It's the mechanics that I can't decide how much to say. We already talk about different families/ two mummies/two daddies/single parents etc. And we talk about consent in a basic form such as listening to people, stop as soon as someone asks you to. Even if the person isn't able to speak (talking about baby sibling but trying to plant the seen for later life) you must still stop if it's not clear they are happy etc. He's clear on the pants rule and secrets vs surprises so it really is just how much and what to say re babies that I'm struggling with - please don't judge too harshly!!
