Field Museum -- might be a little boring for some of the little ones, but if they are patient and enjoy quietly walking around, looking at old stuff and diaoramas, they'll dig it. The dinosaurs will only take you about 1/2-hour to an hour to see.
Art Institute -- Again, if they dig art; it is a great museum. But it's a lot of walking around and looking at paintings and other stuff the little ones can't touch.
Children's Museum (on navy pier, correct?) -- correct. If you go there, plan on either taking a bus or cab, or on paying $20-25 for parking.
Adler planetarium -- Embarrased to say that I have not been. But my kids went with their school and loved it.
museum of science & industry -- The greatest museum in the world. We have been 10-plus times with the kids and they still get excited whenever we go. There's a TON of stuff to see and do there. For the grownups too.
As to children's theater: Where are you staying? Downtown, near downtown or out in the 'burbs somewhere?
This theater has a pretty good Children's programing, but the only thing that I can see running there during Feb. is this:

Hope this helped.
