- Yo crecí con mi madre = I grew up with my mother
- Yo crecí con mi mamá = I grew up with my mom
"Crecí" is the imperfect past of "crecer" for the person "yo".
"Crecí" is the perfect past of "crecer" for the person "yo".
You use the imperfect past with habits or tendencies:
- Cuando era chico comía mucho = When I was child, I ate a lot
- Cuando era chico crecía rápido, ahora no = When I was child I grew up faster, not now (there was a tendency)
You use the perfec past for any actions that happened once or few times.
- Cuando era chico comí tiburón = When I was child I ate shark (once or few times, wasn't something frequent)
- Cuando era chico crecí con mi madre = When I was child I grew up with my mother (I lived with my mother during all the growth process that just happened once)
That's all.
