Atheist parents to be

J 👶🏼👶🏼 • Getting ready to become a 1st time mom! Twins!
Hello! I am atheist and my HB is agnostic. Our families and most of our friends are Christian. 
We are not planning on choosing a religion for our child, however when our child is older and able to make decisions, we would love the opportunity for us to help our child learn about many world religions and allow that child to choose if they believe in a god or not. 
I worry our friends and family will purposely (or sub-consciously) make our child feel that Christianity is the only path. 
Suggestions? Ideas?
