My biggest tip is to plan FP+/Rider Swap for the bigger rides you want to do when the baby usually takes naps!
My husband and I rode 7DMT, Thunder Mountain, etc. using a combo of FP+/child swap when he slept, and it worked out great. Otherwise you are just stuck waiting around for the baby to wake up before you can go on any rides/shows/etc. (you can't take a sleeping baby in a stroller into the shows, as far as I know).
