Carolyn Hax: Should favored child speak up on unfavored sister’s behalf?

Carolyn: Mom hasn’t talked to me about this directly, so there’s been no opportunity to suggest she talk to Sis. I haven’t noticed unequal treatment between us siblings before, but maybe I should ask Sis if she has. After thinking about it more, I decided that if Sis asks again, I should be honest that, yes, our parents were more outwardly excited about my kids, and offer my theory that they are concerned about being cut out of the baby’s life so soon. Sis might be able to address that by talking to them.
