Le Beaumont
My 20 month old goes to the French playgroup at Le Beaumont - I think it is good - in as much as it can be for little ones with short attentions spans, given in a strange language. I think the teacher does as well as she can, I'm not sure she could do anything better; but personally we are going to stop as it is too difficult to get to.
We are hoping to get a French tutor in and share the cost (if anyone is interested - we live on the Southside); plus I recommend going to the Parentheses bookshop on Wellington St to get books and songs.
