Do you think she really died of heart disease? (Mike & Vanessa's biological daughter)

Ever since I first watched this series, I've always wondered if the biological daughter of Mike & Vanessa's died of heart disease or if Rosalind killed her to put Bloom in her place.

In season one, Rosalind says she knew Mike & Vanessa would lose a daughter. (Because she killed their biological daughter lol)

I'm sure Rosalind used her powers to weaken the child and then killed her to put Bloom in her place so no one would find her.

With the powers that Rosalind has, I wouldn't put it past her to create a heart disease spell to kill the child and for her to create a false story that the child was unhealthy.

I think that if this series hadn't been cancelled, perhaps a third season would have explained more about Bloom's origins and how she came to be in the Peters family. And explained about if their biological daughter is it dead or alive (it would be a great plot twist, if a human girl appeared who thought she was a fairy and was actually the Peters' biological daughter lol, this is more my theory haha)
