Why Do I Suddenly Sound Like My Dad Now That I'm a Father?
People are neurologically wired to repeat what got modeled to them before they ever get a say in it. You start parenting like your old man because of: 1) social learning theory, you copied the behavior long before you understood it 2) identity foreclosure, you stepped into the dad role without ever questioning which parts you actually wanted 3) scarcity of scripts, you only ever had one template running in the background. The kid isn't testing you. Your own childhood is.
What's actually happening
You become a dad overnight, no manual
Old patterns from childhood auto activate
You repeat the line you swore you'd never say
Your kid becomes the mirror you can't dodge
How fast old patterns resurface
Nobody tells you which parts of him you actually want to keep.
