I have a 3-year-old boy who has AMAZING language and some VERY interesting speech patterns ~ some typical phonological, some quite atypical. He stops word-initial sibilants /f, v, s, sh, z/ but he INHALES those same sounds in medial and final positions, using correct tongue and lip placement. He seems to understand cues like "make the air come OUT", but at the same time, he's only 3 and has an immature grasp on abstract concepts like that. He's quick to overgeneralize, and I can tell he's been working on it at home (maybe a little too much?) because there's a lot of "s-s-s-s-mouse" (exhale initial false /s/, inhale final /s/) for mouse (for example). Otherwise he's showing signs of classic remediation of the initial stopping, such as "s-s-s-s-tilly" for silly. I guess my questions is HAS ANYONE ELSE EXPERIENCED THIS INHALING THING??! Does anyone have any magic tricks for me with this little guy? HELP!!!!
