<human>: Can you condense the text into a few key points?

Some background: My mom converted to Mormonism when I was 2 and I was brought up in the church. After thirteen years of hypocrisy, bigotry, and endless amounts of guilt every time I didn't "Choose the Right" I apostatized at 15. I'm now 23 and haven't set foot in a church since then.

My mom still goes to church and I don't have a problem with it, she's an adult and can make her own decisions. However I decided early on that I don't want my five year old son brought up to be religious because of my experiences with religion. I recently discovered that when she babysits him overnight she makes him pray with her before bed. 

When I found this out I immediately stated that I was uncomfortable with it, which led to my son having a melt down because he suddenly wants to pray. She's indoctrinating him against my will and I don't know how to get her to stop without severing contact. If anyone has any ideas about how I can deal wit this I would deeply appreciate input.
<bot>: My mom is indoctrinating my 5 year old into a religion that I don't believe in. How do I convince her to stop?
