I don't know. I was just in MGM with my nieces and nephews last week (ages 3-7) and they got a little bored with it all. A little kid can only sit through so many shows without getting restless. It strikes me more as a film buff park. Playhouse Disney was cute and Muppets is a fun 4-D show, plus Woody & Buzz were there at the Toy Barn. However the BackLot Tour and Animation Tour does get a little long n the tooth. And under 3's won't be able to ride Star Tours or ToT. The wait time for Fantasmic is insane, even in the off season. The Great Movie Ride is really a snoozefest, even if the Wizard of Oz sets were gorgeous. MGM has become our least favorite park.
Animal Kingdom has the animals (safari, petting zoo, conservation walk-thru, two other walk-thru zoos), two shows (Lion King involves the audience and drafts some kids for a musical parade, Tarzan is a high-flying show with lots of action). You have a 4-D show in the Tree of Life (Tough to be a Bug), but that may get scary for some little ones. My then 1.5 yr old nephew cried when they turned off the lights and dropped stink bombs on the audience. But DinoLand has a whole carnival kiddie ride set including a Dumbo-esque ride and carnival games. And it features the Boneyard Playground which is cool for kids. The can slide, dig up fossils, climb, etc.
EPCOT has the Living Seas and show with Crush the Turtle. The Imagination Pavilion has the Figment ride and the 4-D show, Honey I Shrunk the Audience. Universe of Energy takes a tour through Dinoverse with animatronics but is not scary like AK's Dinosaur. Mexico has its boat ride ala It's A Small World. The countries have various performers to entertain (the Chinese acrobats are a blast) and the KidCot stations for making crafts.
Magic Kingdom is a given, but be warned that FantasyLand gets crowded fast. Usually you have 45-60 min waits for rides between 10am-3pm or later. Many kids want to ride it NOW!!!! and don't understand why it takes so long. I usually hear the most parent-child fights weaving through there. Get there early, do a few rides, then skip to another park section. Return during parades and fireworks, or try another morning.
If I only had 2 park days, I'd probably do MK and AK for the kids. Personally, I'd do MK and EPCOT. MGM is becoming my "Oh, do I have to" park.
