This is one of the recommended places in Paris to bring children and while there are many interesting things and exhibits to see, the over all handling of guests can be much improved.
Perhaps because we visited during peak season for school children, the museum was full of kids on field trips -- and it was noisy and not well managed, by both museum staff and chaperones of the school kids.
Some of the exhibits were not working and there was no one to manage the lines of kids at the more popular displays.
The science museum for adults is more geared to teen agers and high school students.
