Before the Boy Wonder was born, when we were predictably naive, excited and terrified about what awaited us, the Duchess had a stack of books by her bed about giving birth. One night, I had a rummage through the most modern-looking manual: I fully expected there to be only a small chapter for men and I knew the word ‘father’ would merit only a few direct references in the index. That was fine. What surprised – and angered – me was that the chapter was a preachy, patronising, poorly-written exercise in persuading the prospective dad to realise he had responsibilities and try to make some kind of contribution. I didn’t need telling. What I needed was some practical advice about what to expect and what I might need to do, in the first week, the first month and thereafter.
