We've taken our son wheb he was 6 weeks, 3 months, 9 months, 13 months, and we'll be going at xmas when he is 16 months. Biggest advice is to takei it slow, take advantage of the baby stations at each park, and try not to cram alot in. You might want to go back to the resort at mid day and take a nap. Do a search for posts by me and you can find some of my thoughts on trips at each of my son's ages. Have a great tripand enjoy your little one at Disney!
