Do you have rules?? Door open, door closed?? Ds has his gf over and I can tell he really likes her as never normally invites them around. They have just gone upstairs and closed the door!! I'm trying to be a calm mum and not freak out but I really don't want to be a granny before the age of 40!! Help!! Am I being stupid leaving them to it I mean they will do it anyway if they want to I guess!!
