We just recently passed the 1 year anniversary of our daughter's diagnoses. In all honesty, we didn't notice that the date had gone by at first. A year goes by so fast and to see how much our daughter has changed and grown is incredible.
A year ago, she would hide at the playground away from the other kids and had zero desire to interact with them. Now, we go to the playground and she will run up to every kid she sees and will ask them if they want to play with her. She loves the idea of being with another child and has already started asking about sleepovers. I always hoped this would happen for her, but I didn't think it would. I am so happy I was wrong.
A year ago, we had to walk on eggshells all the time. We were never sure what would set our daughter off into a meltdown. We would say "no" and the screaming would last twenty minutes. We would say "yes", in hopes that it would prevent the meltdown, but even that would set her off. Now, she has learned to use her words instead. Most of the time we can avoid the meltdown, and she is able to communicate with us. We have also learned better ways to communicate with her. This area is a work in progress, and always will be, but there is progression and that is what matters.
