I think it's odd, as she isn't family. Like, very forward of her -- even if you are close friends. I understand the family tie to various churches and the historical roll church can play in family units, but I think it was inappropriate to ask you.

My husband and I are definitely not religious. My mom is Lutheran. Their church allows infants to be baptized (some Christian churches don't do this until much older, or adult when one can make a decision for themselves). She was hoping to have our kids baptized, and we permitted it. We live in a really religious area (from our pov some of them are boarder line cult-ish). Our reasoning being that its hard to get away from Christianity and we would rather them learn of a version of God that is a being of Love and Acceptance rather than a hateful bigot. Additionally, we wanted them to be ok with other people being religious etc even if they aren't, in order to better understand where people are coming from and perhaps help avoid or solve conflict. So when Grandma is in town they go to her church and learn about things with an open mind. And meanwhile while they are with us they learn about other world religions.

I think a light religious approach is ok, spirituality can be an important tool of hope, and reassurance when kids are young and scared.
