I would think you could take a 7 month old on IASW, Peter Pan, Pooh, TTA, Buzz, Pirates, JC, WDWRR, into the buildings in Toon Town, Rio del Tiempo, Maelstrom, Spaceship Earth, Voyage of the LM, Backlot Tour, GMR, Safari, ITTBAB, and I'm sure there are others that I'm forgetting. These are all rides where you can probably keep a baby on your lap.
