repetition

Mum's asked me the same question about her grand-daughter for 3 days running now: "I know J was born in March, but what day is her birthday?"

Each day I've gently coaxed her to remember whose birthday really is in March (her Daughter) and she eventually remembers that it's M's. I give her the girls' birthdays again, only for us to have the same conversation the next morning when her head goes into re-set mode.
