I had my DC christened purely to give something to my parents and grandparents. They are religious and were quietly desperate for the ceremonies to take place.
They were pleasant enough occasions, though without significant meaning to me, but worth it to see the happiness my family took from the events.
All I asked was that we didn't hijack a sunday service - so we went when the churches were empty.
The babies received the usual array of traditional but useless knick knacks - silver birth certificate holder anyone? - and I laid on a nice tea.
I have no idea if the godparents had themselves been Baptised/Christened - didn't ask.
A humanist welcoming ceremony in the garden appealed more, but I figured I owed my parents something after denying them one of the other biggies - a wedding.
