I usually wonder about the babies at the park. It just seems like a lot of work to me! I think it's just fine that parents stay late and let their children, whatever age they are, fall asleep in their strollers. Gotta take advantage of every minute you have at DW, after all!
And I know that everyone doesn't have someone available to take care of their babies (0 - 12 months old) and go to Disney World without them, but I sometimes wonder why some parents bring babies that small anyway.
For me to take a baby that small to DW, I would have to know that my days on earth were really numbered, if you know what I mean, and this was my absolute last time in my whole life I would be going to DW!
But then again, maybe babies are brought into DW by the parents who live real close by, like in Orlando itself, and they didn't have to travel 1000 miles like we do!
