DD (3.8, so still young) still very much has a lot of what I suspect is echolalia and delayed expressive language. We are awaiting an ADOS assessment later next month. She also has a brilliant memory and has memorised a large number of her favourite story books, word perfect. Increasingly she is spending a lot of time just wandering around reciting book after book to herself or her stuffed toys. She doesn't seem outwardly or obviously anxious, but I was wondering if behaviour like this could be a symptom that things, somewhere, somehow, need tweaking? Or maybe it just comes under the umbrella of "mad 3yo behaviour" and I am being paranoid....
