Questions & Answers about Mój wnuk mieszka teraz za granicą.
In Polish, possessive pronouns agree in gender, number, and case with the noun they modify, not with the speaker.

- Therefore you must use the masculine singular nominative form of “my”: mój.

- moja – feminine singular (e.g. moja wnuczka – my granddaughter)
- moje – neuter singular OR non‑masculine-personal plural (e.g. moje dziecko – my child, moje książki – my books)
So:
- mój wnuk – my grandson
