From what I’ve read, biological parentage can get preference even if the child had been living in another household. You’d think what you said would be the case, but state legal opinions are not a thing I would be super trusting of if I were in that position given how our rights are in a precarious position, to say the least. IANAL, but everyone should write a will. That’s better than letting lawyers and judges guess at what you want.
Sweetened, doesn’t particularly matter with what. Though I think my favorite has been a honey/citron/ginger tea from Costco. No caffeine, but the flavor was immaculate.
