Wimbledon - playgroups or activities for 3 year old to relieve tired Grandparents! Can anyone help?

[Rathernew]

My parents will be looking after my 3 year old and 11 month old every Monday and Tuesday from January. My parents are both active but are in their late 60's and I'm afraid the kids will wear them out. They certainly wear me out when I have them all day!

Can anyone suggest playgroups that run on these days withon walking distance of Wimbledon, Wimbledon Park, or Southfields Stations?


Even better would be a nursery where I can use some of my son's free nursery hours (he's only taking up 9 hours so far) but not have to pay top up fees. Do these exist in Wimbledon? I've done a fair amount of googling but failed to find any.

Any suggestions would be very gratefully recieved.
