Playhouse Playgroup is a wonderful Playgroup in the Romany Scout Hut on Lyford Road. It takes children from 18 months to 4 year.
Its a truely magical place - I'm now there with my 3rd child and in the 9 months when my youngest was growing old enough to go I felt bereft as its such a familiar enrivonment. They also do cooking, football, dancing depending on the day you go which saves you signing up to do that separately. http://www.playhouseplaygroup.org/
