How long are you going for OP, as you seem to already have a very full calendar? Please try to relax and enjoy yourselves as well.
I have only two tips, one is try to speak as much French as possible, if you have school French, and a phrase book, please use them even if you think you sound silly - you may well be teased by any waiters or shop asdistants etc - but they should all appreciate your attempts, as they mostly hate people assuming that they can speak English, and they probably can, but they won't want you to know that! Oh, and if you can read any French, try to check whether any restaurants or coffee shops charge more for window and outside seats, many of them used to, so probably still do. Also, some restaurants have (monetary) tips built into the bill, so try not to tip twice - they won't mind, but your purse might!
The other tip is just a strong reiteration of what PPs have said, be very careful that you and your DD guard against pick pockets. If your hotel room has a secure safe, maybe leave your passports in there, but before you do, check (preferably before you go to France) whether you need to have official I.D. on you all of the time, if you do, it might be better to keep your passports in bum bags under your clothes, and any excess money there too. Apart from that, try to wear outer clothing that has some zip pockets, and keep them zipped, and keep checking them. As at least one PP said, have cross body bags with zips instead of handbags, and never carry anything on your backs - unless you have a snappy Miniture French Poodle zipped inside! When I was last in Paris, the escalators from the Metro (underground) were particularly rife places for pickpockets, and especially if you were also at a station servicing places like the Eiffle Tower.
I do hope these precautions don't put you off @Catnuzzle, I think we would all advise the same for any major city, including London, it is just a very sad indication of how the world is today. I hope that you both have a wonderful time, maybe you could come back and tell us about it afterwards 😊
PS. As long as your DD won't be too embarrassed by almost full female nudity, you should both enjoy the show at the Moulin Rouge. I don't know if it is still going, but in the days when I went to Paris, you would not want to take your DD to somewhere like the Crazy Horse Salon...
