Please?
Family units these days can be very different from the "normal" set-up. Grans can be replacement mums, so can aunts, so can neighbours in fact (my mum's elderly neighbour looks after my mum like her own child) so why shouldn't there be cards available for these other women?
I send one to DSM from DS. I've never had a mother/daughter relationship with her but she is fantastic as a gran to my son. She never had children of her own and it stings for her a bit. I feel that she should get some recognition for being a lovely grandMOTHER so she gets a flowery card and a bunch of daffs from DS. She loves it.
Stop moaning you miserable toads.
