I have sewn for many years and when my 1st granddaughter was three she called me nama. She would stand beside me as I was sewing, singing a little song she had made up. Sew nama, sew fast nama, sew nama sew. She's 27 now and all of the grandchildren (all 10) still call me nama, it has stuck with me like glue and makes me feel happy to be a grammie.
