I am pretty comfortable at talking my way around most topics in French (put me around the table at a dinner party and I'm good to go) but one thing I knew I would have a vocabulary gap around was baby talk. Chattering about winding, weaning, splashing in the bath or expressing emotion and doing so in language that can be directed at a young baby rather than in the adult terms I have been used to using.
I have also scratched my head as to what a French 'squeak' might sound like or a French 'splash' or how one would talk about blowing raspberries etc The answer :- 'squeak squeak' is 'pouet pouet', 'splash' is 'plouf' and the French don't talk about blowing raspberries - they just make the noise...not a framboise in sight.
There is no other solution here than to try my best to fill that gap and that's what I have been doing, diligently, since this adventure began. There are so many resources out there (TV, radio, books, the Internet, friends, magazines) and I have found it has simply been a case of working through as many of them as possible. I have started a list on the side bar to the right of this post entitled "French Language Resources" where I have begun to upload details of books and CD's I have found to contain useful language. I will keep adding as I go.
The dictionary has become my best friend and I also make sure to ask French friends for help with the more obscure idioms that you just can't make up.
