I try to remember that one's children are like holidays ? fascinating to you, boring for others ? but I still break out the photos at every opportunity. I insist on changing nappies in public, I play loud rough-and-tumble games in close proximity to childless couples, I think my daughters are very bright for their ages and better looking than my mates' kids (heinous, I know), and am quietly chuffed when a toddler starts roaring and mine remains placid. I also own a pavement-hogging, off-road-capable baby-buggy imported from America, which was bought simply because Tom Cruise has one.
