I got an app called SnakeKeeper for my iPhone, because all three of mine are on 5-day feeding schedules and they are not all synched up on the same days. I can set a reminder on the app for each snake, down to the time, so I set it to the time I need to take out the feeder to defrost so that it is ready for feeding time. It has helped me stay on schedule, and has freed up some "brain space" from not constantly checking the calendar. I hope your parent is on the way to recovery. Let go of the guilt!
