Thanks for all the organising you do for Playgroup at the Timber Lodge. The kids have a really good time there and it connects a lot of the parents in the area.
I'm sure any of the mums and dads that go to Playgroup would be happy to help you out on Mondays. It's not time or willingness that is lacking but the problem is that they are usually by themselves with a baby/toddler in tow so it's hard to do anything while pushing a buggy at the same time.
The only thing I can think of is if two mum/dads help you and one of them is actually looking after the children while the other one is helping you with the logistics of Playgroup.
Any other ideas out there?
