I moved back home a year ago to help my dad care for my mom who was diagnosed with dementia about 3 years ago. My dad is 81 & 10 years older than my mom. My mom had always done the cooking, cleaning, shopping, paying the bills while dad takes the garbage out & does all the yard work. It's been hard on dad so I moved back home & found a job close. Some days, or should I say, some minutes, mom is good & like she's always been. Then the next minute she grabs her plate of food & throws it outside & demands dad take her out to eat. Then the next day she's telling me how much she appreciates that I'm there & cooking for them, even though I made the exact same meal that she just threw out the door the day before. How do you handle that??
