I was very surprised that my son has completely stopped freaking out over loud noises. The lawn mower would have him in a fit of panic, using my Thermomix was like torture to him, electric toothbrush, hair clippers, even the loud noise of the air coming out of the vents in my car with the air con on (we would get in the car and he would scream please turn it off mummy!!).. he just miraculously became oblivious to these noises that affected him so severely once failsafe. He's even started letting the plug out of the bath now, which he never did because the noise of the water slurping down the drain was too uncomfortable for him. We had our first tear free haircut last weekend! I never would have guessed that to be food intolerance related. He's also not stuttering anymore - he would get stuck on the first word or two of a sentence if he was overwhelmed and repeat it over and over unable to finish the sentence. It hasn't happened once since we started. My son used to scream at me NO DON'T SING MUMMY if I tried to sing along with him to a song. Ok with his own sound but not that of others – Ash
