I too thought that Disney changed your kids ages as time went on. However, I remember when my DD was about 9 they stilllhad in in the system still as 4. I was surprised and had them change it. (THe CM told me they don't automatically change them.) The next year we were there when she turned 10 and I asked for her to be counted as an adult at the start of our trip. The CM said he had already done it. Since we were getting the free dining I was happy to go ahead with her age being advanced. Had we not been getting the free DDP I would have had her stay at 9 for the entire trip.
