I've just had my 12 week scan and want to tell DS1 that we're expecting DC3 but am putting it off as I know he'll have lots of questions that i'm not sure how best to answer. He'll be excited about a new brother or sister so I'm not worried about that it's just all the biological stuff! He knows babies grow in muumies' tummies but I know he's going to ask how they get there etc. I want to be as honest as possible but don't want to overwhelm him so wondered if anyone had any advice/experience to share. Are there any good books out there? We have a couple from having DS2 but they are quite young ones.
Thanks
