If you're free on Wednesday mornings the NCT run a weekly walk up to one of the Commons.
It is really friendly and non-members are welcome.
We meet between 10.15 - 10.30am in Crumpet on Northcote Road then head up to either Wandsworth or Clapham Commons, stopping at 11.30ish to feed the kids and ourselves.
My daughter comes along and is 16 months...we also have a few newborns....so regular stops for food, legs stretch etc are expected
Maybe see you then.
