DS is already on Ritalin for his ASD and ADHD.

Today I was chatting to the school's head of special needs learning dept and she vaguely mentioned that there are other anti anxiety meds available other then Ritalin.

I am googling but I was wanting to hear from other parents about what anti anxiety meds their child/ren are currently taking.

What are they?
How are they different to Ritalin?
What do they do for your child/ren?

I just want to put my feelers out for now but any info would be great.
