What do your kids call your parents?

Ar

Me and my siblings have always called our grandparents grandma and grandpa on both sides. My mom decided she wanted to be called Yaya and my dad would be Called Boompa. My husbands mom is Nani and his step dad is his name (or PawPaw but I don’t like him so my kid can decide when he gets older) so my child will call my grandparents grandma and grandpa with no confusion
