Paris?!! I need your help!

We might be moving to Paris! I know, that made me squeal too :) I say moving, but really it will be a long stay to start with--a few months, that is. We have some apartment options, furnished vacation rental options, but I need help with some other things like what in the world to do with a 3 year old! I've found my spots in London that are good for Lois--the playgrounds and parks (of which there are many in London), indoor jumpy play space, water parks in summer, and right now she's in nursery 3 days a week and loves it. But in Paris I'm not sure what to do nursery-wise. She does not speak French (uh, neither do I, but that's another issue). So for now, I'm mostly interested in fun things to do with children near the 4th and 11th arrondissements since that's likely where we'll be staying. We also want her to learn French. I found a baby languages place that teaches children English, but we have that covered. I emailed them to see if they also teach children French, but I haven't heard back just yet. And if you live in Paris, will you be my friend?!! I'm not going to be shy. Moving to another country is hard, and I will need some friends! Same for Lois--if you have children, even better. Lets go play. And get a pan au chocolat while we're out, of course! If you have any other tips, suggestions, recommendations for anything Paris, on any other topic, feel free to let me know that too. I'm all ears, ready with a pen. The photo above is from this great blog post from Kiss My Spatula. If you like Paris, seriously head over and see those photos!
