Thanks for the responses! I thought I had posted a response yesterday but I must have had a hiccup on my phone.
We would really prefer to not lose an entire day or a half-day in Florence as our time is pretty limited. I saw that there are two other flights that *might* work. There is a 7:05 am flight from Florence-Paris, CDG which arrives at 8:55 am and then a 10 am flight from Florence-Paris, CDG arriving at 11:50 am. Would either of those be okay or is that still too risky? Obviously, the 10 am flight would be optimal so we could sleep in a bit more.
If we do fly in the evening before, there are flights through Vueling and AirFrance. Arriving late in the evening, with a baby and then having a flight from CDG at 5:00 pm the following day, what area in Paris would it be recommended for us to stay in and then what time would we need to start heading back to arrive at the airport? It seems like it would give us a morning to do something in Paris but it would be good to find a hotel where we could leave our luggage for a few hours and visit someplace nearby.
Thanks for the help!
