These topics should be taught in schools.
I have one son who is gay, and he lives with his civil partner and their adopted little boy. On the way to school one morning, our grandson was asked by another child why he hasn’t got a mummy. Our grandson didn’t answer, but became very clingy. The answer he has been taught is ‘I do have a mummy but she couldn’t look after me, so I live with my.........’ This why these subjects must be taught about and discussed at a very early age. Every child has the right to have his or her family situation accepted and included. Every child has the right to feel normal, and his/her family situation totally accepted. With these lessons, hopefully every child will feel included rather different.
