Maybe?

So basically my daughter (5) has been marrying her toys and dolls etc. She only marries girls (lesbian couples) so i was wondering if this may be a sign to remember for later on when she gets older and starts dating? Could it mean something towards her preferences later? Or am i just overthinking it. Sounds like im worried about her not being straight but thats not it at all. Just want to try to help her through it and teach her how to deal with homophobic people when the time comes.
