DS is 3 and has started repeating the ends of words. Speech was very delayed and we've had lots of issues due to significant hearing problems from a young age and has only been talking for the last 6 months or so. But we've really made progress and are able to understand him completely now a majority of the time.
However he has randomly started repeating the ends of words. Example "mummy put it back, ck ck ck ck ck." "where's my T. rex ex ex ex ex" it started almost overnight and he does it most of the time now. Should I be concerned?
