Difference between "parents" and "both parents" [closed]

Solution 1:

It seems that a child could be adopted by more than two adults, although it would be very rare and would have to reflect very special circumstances.

So strictly speaking, both in the phrase "both my parents" is not necessarily pleonastic.

Even in the more standard two-parent situation, this might be done for the sake of emphasis or because of the context, which you have not provided.

For example, Year 6 (Grade 5) kid shows symptoms of Covid-19. Teacher says she'll call your Mum to collect you. But she's at a conference 300 kilometres away. All right, I'll call your Dad. " No, both my parents are at the same conference."

You don't need to say "both", but most people do.
