We just love the Natural Science Museum in Raleigh. My kids are a bit older at 6 and 9 but there's stuff for the younger set too. AND its free!
They have a calendar for young children with some programs that are reasonable ($6 per child/parent pair) ;
Especially for Children • Calendar of Programs & Events • NC Museum of Natural Sciences (http://naturalsciences.org/calendar/children.html - broken link)
And check out the discovery room hours. Its a hands on kids room with costumes and all sorts of fun play.
