What defines a Christian upbringing?

I’ve been up and down with the mood swings again lately and Michael asked me this afternoon how I managed before I had God (i.e. before I “became” a Christian). The more I thought about it, the more I realised that I never had to. I didn’t grow up in a church-going, Bible-reading household but my mum would occasionally sing songs from her Sunday school days (“Jesus bids us shine” is one I particularly remember) and I’d pray before falling asleep at night. Maybe it wasn’t a Christian upbringing in a stereotypical sense, but God was always part of it.
