tbh I'd be a little worried about school catchments in that spot. Have you asked on se23 mums Facebook group? I think you'll get feedback there from parents who've been through this over the last couple of years. Check also the Horniman school bulge years as normally 2/3 years after a bulge the catchment shrinks because of the siblings. Re nurseries get on a list ASAP. I'm still waiting from a call from
The rubadubs waiting list some years later . Good luck, Forest Hill is a great place for families
