My social workers have been so brilliant. My ds is profoundly deaf. We only have one toilet in the house and it isnt easy to have a bolt on the door in case he locks himself in when angry and breaks things turns on taps, floods etc...
They came last night and gave me a portable doorbell. I take the press bit in the bathroom with me, the box part stays on the shelf on the landing. If Wilfred wants to come into the bathroom(or bedroom) he has to now knock on the door, i get out of bath/bed put on dressing gown/towel, then press the button. The noise then goes off outside and then a flashing light so he knows he can come in!Genius!! I do have to say though that the noise is deafening! He can hear it with his aids in!!
