I was just reading through this thread and hope you don't mind me posting about kidsunlimited day nurseries.
We have two nurseries in the Balham area, one on Northcote road which is a lovely brand new nursery, Gareth the nursery manager would be happy to show you around if you would like to pop in any time. We also have a nursery just next to Wandsworth Common, again this is a lovely spacious nursery, the manager Kay and her team will too be very welcoming at any time.
In all of our nurseries we have a large outdoor space for the children to let off steam! We hold a range of activities both in and out doors and so they can explore all areas. We also have on-site chefs in each of our nurseries providing healthy balanced meals for the children daily.
Please take a look at our website for more information on any of our nurseries http://www.kidsunlimited.co.uk/
Thanks and Happy Easter!
