I know to some extent perspectives just differ, and not everyone will like Disney, blah blah.
BUT I think this is more about your children being really very small! There is a whole lot of childhood between 3 and teens 😂
Paris is the only disneyland I know, I've taken my kids at variously 3, 4 and 10. I've felt that either they have always been exactly the target age, or otherwise it must be great for all ages which is why we've not hit a 'bad' age yet. They were 4 and 10 when we last visited and honestly there were very few rides we couldn't (all) do - Space Mountain, Indiana Jones, Crush, Tower of Terror, RC Racer and Rock'n'Rollercoaster. And tbh I was on the fence about Crush, we walked past when the queue was at 5 mins(!) and I was tempted but I just couldn't work out how intense it might be and was conscious I couldn't have both children sitting next to me so higher stakes if it was a bad idea! Literally every other ride was good for us at least once.
My eldest at 3 also didn't do Big Thunder Mountain, Parachute Drop or Star Tours.
I imagine at 10 months options are much more limited though and some of these do have really long queues (Peter Pan, Dumbo etc) whereas Pirates, Phantom Manor, Cars, Flying Carpets, Slinky Dog have v often been queues of 10 mins or less when we've visited.
I agree the 'fast' food is shit. It's a shame because some of the table service and buffet restaurants really are great, but Paris aren't yet very good at ensuring people know to get these booked well in advance...
Obvs with all of that, preferences still vary and you don't have to like it, but I can't agree it's oriented to teens and adults. The major UK theme parks definitely are, if you compare eg Alton Towers or Thorpe Park the difference to Disneyland Paris is huge in terms of the thrillseeker:family-friendly ratio.
