she brought me up

[keannu]

One of the most influential people in my life is my cousin. When l was a three(three or a three-year-old) she brought me up because my mom got pregnant at the time.
==================================

1. Can you say "a three-year-old" as a noun to indicate someone's age? Is it common or will just "three" do?
2. If your relative took care of you during your mom's pregnancy, can you say "she brought me up"?
3. I think "at the time" isn't proper, it should be replaced with "at that time or back then", right?

1. You cannot describe someone as a three to indicate their age. You need the hyphenated compound noun three-year-old.
2. No. She brought me up means she was your primary caregiver until you reached adulthood.
3. It should say at that time or just then.

If someone worked like a nanny for a baby during the mom's pregnancy, can you just say "she(nanny or someone else) took cared of the baby" or "she brought the baby up"?

2. No. She brought me up means she was your primary caregiver until you reached adulthood.

She took care of me when I was three, during my mother's pregnancy.

Why can't "back then" work here?

Why can't "back then" work here?

I'd say "because my mom was pregnant" - not "got pregnant."

"Back then" doesn't work because you said "was," so we already know that it was back then. Saying "back then" is redundant. It just clutters the sentence.

It's not about grammar, it's about logic.
