My dd has been great in her speech development and seemed to be ahead of her peers until around 2 months ago when she developed a kind of stutter.She sometimes gets stuck on the first letter of a word but it's more of a mix of repetitions in her sentence. She say something like M m m m mummmy, wwwww will you get get get get get me me me me an ice cccc cream please. Sometimes it seems like she can't think of the next word and sometimes she just gives up. If I ask her if she wants a cheese or jan sandwich, she'd say ch ch ch ch ch....jam because she realises she can't grasp the word. Some days she's fine and no one would notice her being any different than any other 3 year old, then others she can barely string a fluent sentence together. It seems to have come on out of the blue and comes and goes with more bad days than good. I'm getting worried that she will have a permanent speech issue. Has anyone come across this before?
