My mom is caring full time for my 86 year old grandma with dementia. I have a 5 and a 9 year old.
In some ways, our journeys have been remarkably similar in caring for the 5 and the 86 year old. We were both dealing with diapers, temper tantrums and spilled food at the same time. The difference is, the 5 year old grew out of diapers, and is getting better about the spilled food and the tantrums. My Grandma is not, in fact, she's getting worse.
As much as I love my mom and try to help her out, I would not switch places with her.
