When our oldest grandson was born, he had 8 grandmothers and greatgrandmothers. My children call me 'mama', so I was going to be 'granmama'. He couldn't say it plainly, and called me 'meemama'. He is the oldest of 11, and I am still 'meemama'. My user name here is the-meemama. Half the kids in town call me that, too.
