I remember the days of kids outgrowing *everything*.
But what I wanted to comment on is the MASKS. The cloth ones are super cute, but I found the disposable ones more practical for Disney. This way if they get wet (water rides, rain) or sweaty, it's an easy change as they take little space in a bag. Also, no need to wash them. Just toss at the end of every day.
Oh, and if you have any mask chains, those are so helpful, too. That way, when you eat, you can just take off the mask without needing to lay it down anywhere.
