In my experience of being a mum of 3 and a language teacher with the added bonus of being French, living in England, we have never found suitable language learning materials of any sort to help us out when the children were pre-school. I have spent time designing our own materials then and was so busy living that i didnt realise that it was also a problem for English families trying to learn French.If you are living in GB at the moment try to find out about "L'Escargot", they run activity clubs everywhere in the UK under their Franchise and are very good for young children.If you live in London there is the Lycee Francais Cromwell road where they take children from 3to 18. About half the price of English Private school fees.You could look into getting children books and magazines through subscribtions some for that age range come with a story,tape or CD and could be a tool you could use. I will keep on thinking on the subject and hope to come back with more ideas.
