My 3 year old neice was pretending to nail my daughter's hands and feet to a cross (like Jesus) and also doing this to her brother. I just found it really strange and felt really uncomfortable with it. I just politely asked her not to do that to my daughter. My SIL said that someone told them they nailed Jesus to the cross so now they play games about it. I don't know that it's a bad thing, it just made me feel really uncomfortable. Would you find it odd or allow your children to play games like that. It's not so much that I was freaked out about it, I think it was more of a respect issue, like respecting Jesus dying on the cross. I'm not sure why I found it uncomfortable I just did. Mind you I am going through a very stressful time at the moment.
