The order of the events in the passage

Dear teachers,

Thank you for your kindness in advance.

I have a question as follows:

[Question] In the passage below, when did the event of the underlined event happen?

1) When Kay Rene was a newborn baby

2) When Kay Rene's mother approached Kay Rene about the subject

The families learned rumors of babies being switched at birth had been around for decades. In fact, Kay Rene first learned of such gossip in 1995 when her sister Carol told her during their dying father’s last camping trip. After his death, Kay Rene’s mother approached her about the subject. She acknowledged that she heard another new mother in the same hospital, where she had given birth, question if her baby was her own. But after looking into Kay Rene’s big brown eyes, she determined this was her baby and she wouldn’t bring the issue up anymore.
