I have been paying for a medical alert service for several years. My dad wears it as a necklace. He says it's uncomfortable when he rolls over on it while sleeping, so he sometimes takes it off and puts it next to his pillow. He has recently fallen several times and will call out for help (he lives in a retirement home) but has never remembered to push the button. Any suggestions as to how to get him to remember? (His Alzheimers is getting worse by the day.)
