What I've learned from working in different schools and at different levels

I started teaching in Higher Education when our first son was about a year old.  I was a marketing professional that went back to the agency i worked at part-time - two days a week.  There was a recession at the time and the client base was shrinking so I started to look at other work and came across a college looking for a marketing professional turned teacher.   

What would I go back and tell myself when my kids received an autism diagnosis

There is no correct way to react to your child receiving an autism diagnosis.  For some parents it can be a shock, others are worried, some are relieved.  It's normal to wonder why or how a child is autistic.  When we were at our first autism diagnosis meeting the first thing the paediatrician said was something like 'it's nothing you did or didn't do, nothing that you did wrong.'
