I have a 3-year old and a 1-year old.... My husband and I want to wait until our kids are a little bit older before we take them to Disneyland. By then, they will be old enough to ride most of the rides and they will be old enough to remember all of the fun.
In the meantime, we have been watching Disneyland rides on YouTube. It is so much fun, especially on those cold winter days when you don't want to leave the house. My kids have been really entertained by it. When we do finally get to Disneyland, they will already know which rides they want to go on first. Try it- I think your kids will love it!
