When Isaac Lappin's son was 18 months old, he wasn't sure he'd ever be able to speak.
"I noticed the first change was within that first 18 months, which is a big turnaround with a lot of autistic kids," Isaac says.
"With that 18 months, the visual signs were like most [autistic] kids — like lining up toys, cups had to be the same, and just little things like that we really noticed.
"Then being non-verbal … back then, there wasn't much help."
