Aloha: Moʻopuna kāne [mo o-poo-na kay-nay]
The Hawaiian word for grandson is "moʻopuna."
You say, "nietos." Arguably, it means grandsons, however, in Spanish, it's how they do "grandchildren," of mixed genders.
Just say it on the phone. Hate you, love you. Either way, you need to get over it. If your out of the house, they can't tell you what to do or not to do. Its their grandson/grandaughter for goodness sake. They need to get over it.
Your granddaughter and your niece's son (the grandson of one of your siblings) are second cousins to each other.

'Grandson' = 'barnebarn'
You can say "I am Hawaiian" in Hawaiian as "ʻO wau he Hawaiʻi."
