Say a woman (let's call her Jane) has a daughter (let's call her Mary) and the daughter (Mary) has a child (let's call the child Carol)

Jane is the grandmother of Carol.

If Jane has a child other than Mary, that child is Carol's Aunt or Uncle and Carol is that child's Nephew (if Carol is a boy) or Niece (if Carol is a girl).

So the relationship between a grandmother's baby and her daughter's baby is that of Aunt/Uncle to Niece/Nephew.
