Fun stuff for toddlers in Paris

Hi everyone!

We are going to be in Paris for a couple of months begining in April and was wondering what and where can I go to entertain a 2 year old toddler in Paris. Is there any fun place or programmes for toddlers in Paris?  Hope to hear some feedback on this soon.

best regards,
Raycillient

I will be going in July for 6 weeks to Paris and am curious if you have any recommendations? (2 boys: 4 and 6) Thanks
