DD1 is 3. We often walk or drive past churches (her preschool is next door to one) and she is curious about what happens inside. When she asked what happens in church I said something along the lines of "People go there to sing songs and talk about how to be good." She then announced that she wanted to go there to sing, and that she wants to live in a church!
I'm struggling with how to explain the concept of God/religion to her, since dh and I do not believe in it. Is 3 old enough to understand that different people can have different beliefs about matters like this?
