Probably 1ish. I remembered me and my mom living in a 1 bedroom apartment on the 2nd floor in St.Croix, before I lived with my other siblings. My other siblings came before I was 3.
I also remember going to Dominica. I went twice, 1st time at 2months old 2nd time at 18months.
I clearly remember hurricane Hugo, and I was before I was turning 3 at that point.
