A former colleague of mine talked a while ago about how he and his wife were getting terrible worried about Doing It All Wrong with their first baby. Apparently an NHS health visitor basically summed it up as "so long as you put food in one end, and keep the other end clean, it'll all be fine", which consoled them a lot.

I guess it's a bit like real life... you can eat healthy food, and go to the gym, and meditate twice a day, and embark on complicated journeys of personal development. Or you can, like, not - and it'll all be OK anyway.
