My 22 month old has been speaking in sentences since she was 16 months and can hold a conversation with me and use reasonably complex 7 word sentences although her pronunciation is poor so others struggle to understand her. In the past week or two she has developed a stammer which seems to be getting worse day by day. I've read stuff saying that it is relatively common to get a stammer for a short period of time aged around two or three, but my father and brother have a stammer, so do you think I should try and get her seen by a SALT straightaway and should I be worried?
