One on my children frequently uses a squeally high pitched voice. Often when playing if its not going their way, if they feel frustrated, if they are not being listened to by their sibling, or if the dog moves away when they don't want them to etc. Its sudden, ear piercing, indignant, loud and really grates with whoever is in the house.
Its driving my husband barmy!
How would you deal with this? If it were direct whining at us we could ignore it so they don't get attention from it but its not. Its aimed at their sibling mostly.
I think its just a bad habit but would like to help them break it.
