My son is 5 and has never met FOB. This wasn't my choice. My son has made comments such as "you're my mummy and my daddy too" and he has mentioned the fact that something's his friends dads pick them up from nursery. He's even mentioned that boys can be daddies when they grow up etc. but he's never actually asked about his own excuse for a father. When did your LO's (who don't have contact) ask about him?
