I'd at least wait until temporary exhibitions are announced to finalize your plans. You can then decide if some are more to your likings than others.
Depending on the composition of your family (old folks, small kids...) spending more than 2, 3, hours in a museum can be hard; take that into account in your planning.
In my experience (in other science museums), you will spend more time in the Field Museum, especially if there are hands-on exhibits (where you can handle stuff yourself)

I would figure one day for the Field Museum, another split between the Aquarium (I've seen better) and the Planetarium. And the third day is for the Museum of Science and Industry. From your description of St Louis, this will be an all-day museum for you. I hope the snack bar is better than when were regular visitors.
Science and Industry is not located on the Museum Campus; it is a leftover from the 1893 World's Fair held on the Chicago Midway. However, there is frequent express bus service from the Museum campus, or elsewhere in the Loop.

Opinion answer for an opinion question:
If I were trying to plan this, I'd spend one day at the Museum of Science and Industry, a morning at the Shedd Aquarium, and an afternoon at The Field Museum. You'll definitely be missing out on exhibits at The Field Museum as there's no way to go through it all in half a day, so read up on what's there and plan your trip accordingly. Alternatively, you could drop the Shedd from your plans... the Field Museum is quite comprehensive.
While you're out by the Shedd or the Field Museum, be sure to enjoy the view on the lake. Fantastic view of the city, which is particularly stunning in the evening!
