Religion and dinosaurs

So my 4.5yr old boy has taken a huge interest in dinosaurs. My question is: my Granny (she is the most sweetest, loving person) who is religious, obviously does not like/believe in dinosaurs. How am I suppose to handle this? She does live about 10hrs away so she only comes a few times a year. I used to make sure to not put my son in any Dino shirts etc when she was around or when I was sending her pics, but now that his interest has really taken off, I can’t really deny him talking to her about them, showing her his Dino toys etc, seeing his room with Dino posters. So what do I say to her to understand? Although she knows I don’t practice religion she does not know I am agnostic. She thinks I believe in Christianity. And no I am not willing to let her know that I don’t. It doesn’t come up much and I wouldn’t want her to be upset. via /r/Parenting https://ift.tt/2GvRJ2Z
