Take the train.
Do not fly.

I was in Paris yesterday for work and my flight was delayed 3hrs coming back. Everytime I go to Paris it is a worse expereince then before. The airport is awful and not what I would call baby friendly.
I have taken the train and I prefer it over fying. Plus you end up right in town when you get off the train so there is no hassel of getting to and from the airport ! Enjoy Paris and hold on tight to you wallet !
