Any ride that does not have a height restriction would be ok for the infants.
Here is a list of the ones they can't ride (most are obvious

)
AK: Dinosaur, Kali River Rapids, Primeval Whirl
( It's Tough to be a Bug might be a little to intense but that is your choice).
MGM: Rockin' Roller Coaster, Star Tours, Tower of Terror (Fantasmic and The Great Movie Ride might be to intense, but again they will not stop you...your choice)
Epcot: Body Wars, Mission Space, Test Track
(Honey I Shrunk the Audience maybe to intense)
MK: Big Thunder Mountain (closed for rehab), Goofy's Barnstormer, Space Mountain, Splash Mountain and Tomorrowland Speedway.
(Haunted Mansion may be a little scary)
On any of these rides you can do the child swap (have someone wait with the kids at the exit and the rest of the group goes through and rides, when they come out the one that waited can go back in (with up to 2 others in the party) without waiting in the line again...just ask the greeter at the attractions they would be more than happy to assist you).
Other than those you are able to take the infants on any rides in the park
O' and be prepared to fold, unfold, fold, unfold the strollers. Most attractions make you leave them outside but there are some, like the Train at MK that you would need to fold them up to ride
Have fun on your trip
