He can talk at a reasonable volume just chooses not to. He is almost constantly shouting at me, his dad, his brother, not nastily just talking at a loud volume and I have had enough. He also talks constantly and always has to have the last word so is becoming quite rude.
I have hypersensitive hearing so its actually painful and overwhelming for me and I often can't be in the same room as him so either find myself walking away or sending him to another room. We are constantly telling him to shush, talk more quietly or even the dreaded shut up (although I hate that with a passion).
His hearing is fine and I think its because he has to shout all the time to be heard at nursery. When I asked them if he shouts there they said no more than any of the others.
I don't suppose its that unusual in a 4.5yo boy but we need ways to cope with it better or at least get him to realise what he's doing so he can deal with it better.
