My child is six and in a mainstream school with the senco involved. Main issues are:
"zoning out" in class
Difficulty following instructions
Social skills are ok, has confidence but being "in own little world" half the time affects social life.
So many things overlap between autism and adhd and we don't have a diagnosis of anything yet. I would appreciate hearing from other parents if your children struggle with similar things. My child is known for being a daydream but I think it's deeper than that now.
