Has anyone got any advice.. my son whose 9 thinks your dad is your dad because he is married to your mum not because they have had sex and created a child. This has arisen because I have re married and he thinks his dad isnt his dad now because of this. Also he was asking how his friends dad could be called his dad when he wasnt married to his mum. I think he is a bit young(?) for the sex talk yet but I'm not sure what to say to him as i don't want to give him duff info and have someone take the mickey at school . Has anyone else had this issue arise????
