Would the "quiet residential" nature of this area be an argument for closing Horniman Primary school, then, due to the school run?

There's a baby boom on. Not everyone is a yummy mummy with Papa earning enough in the City for Mama to stay home. There is not enough reasonable daycare in the area, as evidenced by the ridiculous waiting lists for nursery care (2 years for one which starts taking babies at 3 months!!)

If you want a well-adjusted next generation capable of paying for your pension, rather one of kids who end up going feral because their hard-pressed parents can't get them looked after when they go back to work, so they get used to roaming around at too early an age, then give them, their parents and their potential care/early years education providers a break and get a life.
