I’m Canadian, so not American, but for me it’s because I don’t have the same grandparent support my parents had. We had to move far away to be able to afford a place to live and now we have no help. My siblings and I practically lived at our grandparents’ houses, and so did all of our cousins. I hear a lot about how uninvolved grandparents are lately, whether by choice or by practicality (the distance, for us).
