Sorry this is going to be long lol.....
Princess Disney Mom.......YOU ARE ONE AMAZING MOM!! As a parent living in your shoes (my autistic DS20 seems to be at the same level as your sweet daughter), many have no idea what it's like on a day to day (sometimes minute to minute) basis trying to keep our kids content, safe, and happy. Our son eats, sleeps, breathes Disney (currently watching Wishes on youtube as it is a snow day here in MA lol). His favorite ride is the monorail, followed by Dumbo. We bought him a 5 day ticket and ended up going into the MK for about 3 hours last week during our trip. But that's ok, because it's all about him anyway. He doesn't like to do many activities even at home. He doesn't like bowling (not even Special Olympics activities), but enjoys shooting hoops and other outdoor activities. We used to force him to do activities when he was younger but feel he can make more decisions about his life now....(we also have Guardianship FYI). He never asks for anything (Christmas is always difficult because he never wants anything). Your story rings familiar to me only because of a recent incident with us. He had to have all 4 wisdom teeth out (they weren't bothering him but bottoms were impacted and easier to remove when younger than when older so they say). What an ordeal....from trying to explain what was happening, to even getting him to go into the hospital (he's 250 lbs). He refused the IV, kindly by saying "no thank you"...always a gentleman lol. I knew something was up when about 5 people dressed in scrubs showed up. I have always been strong enough to hold his hand thru anything, but my heart was breaking for him and I started to weep. Luckily hubby was staying strong so I could sneak out of the room to catch my breath. Sadly, before I could go back to him, they rolled him out and into the OR and I could hear him crying from the hallway. I felt like a horrible mother. When he came to, he cried inconsolably for about 45 minutes (which seemed like an eternity). The Doc said that he's mentally at where he was right before he went "under". Ugh no wonder he was crying so much. Anyway, he did recover...tho it was a long long emotional exhausting week after that. The reason I'm telling you this story is because ever since the surgery (or so it seems) he doesn't want to be left alone. For maybe 6 months leading up to his surgery (which was 4 weeks ago) he had started to stay home alone for an hour or so (he knows how to FaceTime from his iPhone, but won't talk on the phone lol). But that has changed. He always wants someone to be with him. We have been trying so hard to figure out why. Does it have to do with the surgery and being wheeled into the OR with strangers? Did something happen at school to scare him? At home? We consulted with school staff to see if they could figure it out but they couldn't either. He IS slowly doing better (hubby and I ran to the market for about a half hour the other day) and he was perfectly fine with it (had he said "stay" we wouldn't have both gone). Guess only time will tell what the future holds. Anyway, even if you can't figure out the "why", I know you will be content with "what is happening now".... cuz' you're already doing a fantastic job at it!!
