Hi, Donna, I am so excited for you to be planning your first Disney vacation! With your size party, the Villas at Wilderness Lodge will be a nice choice. You can stay at 2 bedroom villa that sleeps 6 and has a full kitchen so you can enjoy some meals right in your room. I have stayed at Wilderness Lodge and thought it was great. Your kids will have fun splashing around in the pool and there are wonderful restaurant choices right in the resort.
For other resort choices for parties of 5 or more, check

You didn't say how long you were staying at Disney, but if time allows, try to schedule at least one day for each of the 4 Theme Parks. Your boys are at a fun age that they will want to try so many of the different attractions! My kids are 9 and 5, pretty close to your kids ages, and some of their favorites are Test Track at Epcot, Toy Story Mania at Hollywood Studios, and Splash Mountain at Magic Kingdom. You know your kids best, so go on rides that you think they will like. Your 4 month old will probably be dazzled by the colors and lights all around!
