The kids are taught about relationships from the very first cartoon they see . There ' s always the knight saving the princess or something and they then go on to live together . So concept of people living together is already there . What should be done at this point , is explaining that some couples aren ' t prince and a princess . Sometimes the prince finds another prince or the princess falls in love with another princess . The kid has no prejudice over this , until someone poisons their mind later on with some artificial limits . In many cases they will bring up the kid doesn ' t need to know about sex yet . The problem here is that living in a same sex relationship isn ' t any more or less about sex than living in a hetero relationship , so trying to draw some kind of a line between kidsafe hetero relationship and confusing same sex relationships is just damaging and not helping in any way . I think you were right about standing your ground and you should have a serious conversation with your parents about the whole thing . You might not get through to them , but you might save one 7 year kid from getting their mind poisoned .
