If you can afford to buy in ED I would definitely recommend - 10 years ago we also moved with a baby and we are still loving it - sure you can buy a larger property further away in Bromley, Sevenoaks etc... in a more suburban area but to echo some earlier post and as you probably know the demographics is a bit different. It really depends what you are looking for. With 2 parks, a great community feel, a nearby child friendly museum (Horniman) and good schools... to be honest I don't see where in South London you could find a better place for a young family - maybe i'm biased but I lived in many places from Greenwich to Clapham. Sydenham, Forest Hill and Crystal Palace are also worth considering imo.
