I’ve had this hammered home having just returned to work after a second child: putting my toddler and baby into full-time daycare near my zone three house would cost £38,000 a year (a quote which didn’t even include gold-plated nappy cream: I checked, but they weren’t amused). Working flexibly, though, means I can write in the evenings and weekends as well as when my kids are at nursery, making it financially possible for me, and millions of parents whose skills might otherwise fizzle out, to work.
