Dad can't remember that he can't walk!
I moved him to my home because he kept falling and breaking bones. The rehab place couldn't even put rails on his bed. Now I have a bed with rails and an alarm under his mattress. He still tries to get up at night and if he makes it - he is on the floor before the alarm can sound.
I know I'm very lucky because he has 12 hour a day care and he's still pretty pleasant but I'm scared he's going to hurt himself again!
