Such happy happy news for you!
I took my son at 8 mos., then I took my son when he was 2 1/2 and my daughter was 5 mos, then again when my son was 3 1/2 and my daughter was about a year and half. The most difficult time we had was when my son was 2 1/2. It was just too much for him and we overloaded him by accident and there were a few meltdowns.
We find babies to be so easy at Disney. You have the baby changing stations all over the place where you can nurse or change the baby. My kids slept during all of our dinners. You baby swap on rides they can't go on. And they sleep in the stroller when you are lounging at the pool. I found we could take our baby all over the place, and when he/she got tired, they'd sleep in the stroller. It's when they become mobile that it becomes interesting.
I'm expecting in late Oct, and will be probably/hopefully visiting WDW in Jan-Feb, so I'll have about a 4 mo. w/ TWO mobile little ones this time. Somebody HELP ME!!! Anyway, babies go w/ the flow usually. I wish you all the health and happiness in the world.
