My 3 year old DD has started to make this sort of *squeaking* sound when she's speaking. The sound can also be described as like a floorboard creaking/ door creaking. It's really weird! She doesn't seem to have any control over it and doesn't even seem to notice she's doing it. It only happens when she's talking.
It happens often but not every time she talks.
This has been going on for 5 days now and honestly its starting to freak me out a bit! Google has been no help.
Anyone ever come across this?
