My five-year-old just asked me- Mummy , can two girls marry each other? How am I supposed to respond to this question?

i think you should answer this with an open mind and heart. instead of focusing much on the gender, i suggest you tell her that a grown up can marry any person that he or she truly loves and wants to be with. it can be a man and a woman, a man and a man and even a woman and a woman. in the end, it is important to spend together time with a nice and kind person who you are happy with, and who you are good friends with :)
