Hello, I have a 6 year old autistic daughter who was diagnosed aged 4.
Your goal as the parent of an autistic child is to help them thrive. It is NOT to help them appear neurotypical. Echolalia is something that should be encouraged not stopped. It is a perfectly valid way of learning to talk. The way your child plays now is fine. There isn’t a “better” way to play just “neuro typical ways” and other ways. Imagine if a neurotypical child was discouraged from playing imaginatively and instead told to line up all their toys and play the same way every time? It’d be awful for that child. Encourage his interests, join him in his play and play the same way. Copy what he does. Don’t ask questions but comment on what he is doing.
The More than Words book is excellent so get that if you can. Check any therapist is neurodiversity affirming and is trying to help your child not help them appear neuro typical.
Some resources:
the Nuturing Neurodiversity Facebook group is an excellent and very kind space for parents in your position
NeuroWild is an autistic Speech and Language therapist and she is amazing. She’s on Instagram and Facebook. Please check her out.
Listen and learn from autistic adults.
It can be so stressful being the parent of an autistic child I won’t lie. But to reassure you, at 3 my daughter spoke entirely in echolalia (both immediate and delayed) and showed little interest in those around her. The pandemic hit so there was no SALT anyway. But she made progress anyway. She’s 6 now. Her speech is considered age appropriate, she has friends, she’s doing so well at school, she plays her way in a very rigid way but she also has moments of pure imagination with her sister. Both ways are fine!
