Currently 34 weeks pregnant with mine and DH's first baby
I was not Christened myself, have never been bought up with religion in my life or particularly believing in it and I would never think to have the baby Christened.
My DH was Christened but is not religious. He teaches at a Catholic School (circumstantial, not because he 'believes') and although he attends certain services with the school he otherwise has nothing to do with the Church.
He announced yesterday that he wants to get the baby Christened - I asked him why and he came out with some line like, "It's just what's done isn't it?"
I said that neither of us were religious so what's the point? He then dared to say, "I think my mom would be upset if we didn't...." 
I told him it's not his mother's baby and it's nothing to do with her!!
(there have been previous issues with him wanting to please MIL)
Has anyone else had their baby Christened, despite not being religious, purel as you felt there is a sense in society that all babies should be Christened 'just because' ??
