Thank you all for your tips and advice. We just got back from our trip and everything went so smoothly! Disney does such a great job of making the parks accessible for everyone. Alexa only had a few episodes of real concern, and didnt need to go the hospital. (first time since she got sick we were able to go 10 days without something happening...) We came close once when DH ran over her tube and broke it, but surprisingly it wasnt pulled out of her stomach (yay!). Thank you to the man who helped DH and offered to flag the paramedics. With the GAC we were able to do things and then let her rest so she didnt get too fatigued. We would go back to the hotel everyday so she could nap, and were able to have early days. However we felt were able to see and do everything we wanted too.
Our 6 yr old had so much fun... The most magical time was when she was dressed as Belle and we were dining with the princesses in Norway. Ariel took her hand throughout the parade. What a treat... But the best part of the meal was our waitress. She asked why the baby wasnt eating and if she could bring her anything she might like. We explained a little about our situation. She sort of hustled off, she was very busy. But she came right back with a cupcake with gummi bears for our DD6 with tears in her eyes, saying she wished there was more she could do. What I dont think she realized was that she already did it her kindness made our DD6 feel so special. DD6 still talks about that special cupcake. She thinks it was because she looked so beautiful in her Belle gown
We couldnt have asked for a better vacation. Everyone says not to expect too much so you wont be disappointed, but this exceeded all expectations. So much so that DH and I are seriously thinking about doing the DVC. We got to see our baby come a little into her own without so many MD appts. Our 6 yr old was able to just be 6 and we were able to reconnect as a family.
Thank you all for all your helpfulness.
