Well they would think i'm really crazy then because my husband and I took our daughter for her 1ST birthday! We also brought along grama and grampa and they were a huge help, we all had a blast together! From my personal experience I don't think bringing a 22month old is too young at all. My daughter turned 1 during our trip and she got much more out of it than we expected her too. There is no perfect age to bring a child to Disney, each age shares a different experience and they are all just as magical if you ask me. We brought our daughter on 90% of the attractions we went on. The only rides you will see that your child won't be able to go on are the ones that have drops, or rollar coaster like. Disney is geared for everyone to be able to ride their rides so thats why it differs from like a six flags, where your child wouldn't be able to do much. Aside rides.. there are plenty of other things for your little one to do. We only went to a few shows at the parks but the ones we did, had our little one entertained from start to finish. Character meet and greets are amazing for any ager.. babies to adults, we all get that same smile on our face when walking up to take a picture. The parades will be great for his age also, to see some of his favorite characters singing and jumping around. Having your MIL along will also be a big help, we had grama and grampa along and when our daughter was tired and grama and grampa were also worn out by the end of the day they would go back to the hotel and we would catch the disney night life still. Nap times were never an issue for us.. she napped in her strolelr and we kept trucking, we got so much out of that trip, I would recommend any age is never too young.
