Thanks for responses. My brother has 3 1/2yr old, ex remarried, just had baby. Had issue in past due to BM enforcing child to call SD, just 'daddy'. If the new baby brought up, child immediately responses defending baby is sister, not 1/2...implying this issue must be discussed at BM's home w/ child. Now also child calling step-grands..Nana & pawpaw...Nana being what my mom is called, the bio grand. This is upsetting my mother more than I would have thought. Step grands in town, bio's 1 1/2 hrs away. In turn, my mom is getting my brother, BD, pretty worked up about & u know how goes.....more goes on, bigger issue becomes, more upset people get and on, & on......
Never had problem here, just wanted to get general opinion....see if this problem for anyone else. Thanks again.
