We took my daughter at 12 weeks, 15 weeks, 6 months (DL), 9 months, and we're headed back in April when she'll be 13 months. Each trip was great and she enjoyed being with mommy, so therefore she enjoyed the trips. At 12 weeks we were with lots of family and friends and they all commented on what a good baby Madison was as she never cried, which was true, she didn't cry once the entire trip. Now, I'm not saying she cried lots at home, she didn't, but she was incredibly happy in WDW, I think because she was held all day long (also not a stroller baby at all, so she was worn in a Baby Bjorn all day). She went on every ride without a height restriction (though she slept through most) and saw the parades (she loved Spectromagic!). At 6 months though was when she really started to have fun. She was sitting up and starting to crawl, but not enough that she fought us to get on the ground yet. She loved the characters at that age and started to like the rides. At 9 months, though, she had a better understanding of things, so she had an even better time. She loved the parades (especially when the characters would come over to play with her), 'kiddie rides', and most of all the characters. Even though she is reluctant to let her daddy hold her, she stretched her arms out for ever character and was sad when I took her back! She is breastfed so I didn't have to worry about formula and bottles, which was great, but this last trip she was eating baby food so I had to carry that around, but it was only 2 jars a day so it wasn't so bad. Ad it was all worth it to see her face on the rides and meeting a character. The April trip is probably going to be the hardest as she'll want to get down and walk around!
