How Do I Add My Mother’s Separate iCloud Email Into My Own Mac Mail?

My mother has motor neurone disease and has her own iPad for video communication. I am her daughter living at some distance (with my own iCloud, mac email and Mac Book Pro set up) and manage all her affairs remotely. I would like to monitor her very occasional emails without going into iCloud – and to have her email come into my own Mac Mail. Is this possible without creating havoc?
