When we talk about challenges of autism, we tend to focus only on behaviors. But the real struggles come from deeper root causes. Whether it is picky eating, sleep problems, mouthing or stimming, you will always find an underlying reason for these symptoms. I want you to share your current challenges and we can help each other by identifying the root cause. I'll go first . . I have been noticing that my son would have a laughing fit and soon after, he cries and then goes back to laughing uncontrollably. Three years ago, seeing this kind of behavior was very worrisome for me and that's only because I didn't know what caused my child to do this. Now, I understand that this is a classic symptom of yeast overgrowth and I know what measures I need to take to tackle the issue.
