I have a 2-year old niece and ever since I became acquainted with Astrology, I was a little surprised when I ran her chart.
Scorpio ASC
Moon conjunct Saturn rx in Scorpio in the 12th house (Moon conjunct Ascendant)
8th House Sun in Gemini
8th House Mercury rx in Cancer
And, North Node in the 12th House too but in Libra.

I was told a while ago that my niece probably dabbled in/was associated with dark/black magic and occultist subjects in her past lives and the fact that Saturn is retrograde, it means that she's been repeating the same mistakes throughout her incarnations.
Can anyone give me an input on that? Thanks in advance.
Anything in a chart that could indicate past lives can just as easily indicate ancestral past: the portion of your ancestors' history that manifests in your own life. If the ancestral history is known, clear correlations can be seen. Reincarnation can't be proven or disproven, but history can, if we have the right record. But we don't have the full records. Even if you know who your ancestors were, even if you know something about their lives, you don't know how they lived their emotional, subjective lives. You don't know what secrets they took to the grave.
When the twelfth house is involved--and to some extent, the eighth--the native is living out the secret part of their ancestral past. Houses 4, 8, and 12 are the houses of secrets. In H4, the secrets are open secrets: there are people alive who know and could tell them. Open the closet door, and the skeletons come tumbling out.
H8 is buried secrets, the kind that you could uncover if you dug for them, but you would have to dig. They aren't open secrets. H12 is the completely unknown secrets, the ones that died with people who died before you were born--but they still turn up in the family's collective unconscious, and in the native's life.
In that light, the "she keeps repeating her mistakes through each incarnation" means that she's personally affected by the weight of mistakes that have been passed down through many generations of her family. Maybe, for instance, there's a family history of oppressing others--owning slaves, running sweatshops, being corrupt politicians or tyrannical nobles, or simply a lot of sexism in the family, and/or many generations of abuse. Maybe the family history runs more to being oppressed than to being the oppressor--but in that case, it's a deeply internalized oppression (Saturn conjunct moon).
To be clear, it's not only what her ancestors did, it could also be what was done to them. Saturn in that position, though, makes me think we're looking at some ancestral deeds.
Moon also indicates mother, particularly what was going on with the mother at the time of the native's birth. You just described your niece's moon perfectly in your sister's life: abused, traumatized, in a particularly Scorpionic way, trapped (or feeling trapped) in an unhappy relationship, but possibly about to break free (twelfth house but near ascendant suggests that she'll soon find her own footing, so to speak, even if she's stuck right now; however, the retrograde could mean she's moving back into stuckness), and the thinness and bone disease are attested to by Saturn (rules bones and makes smaller).
Houses
If you look at the medieval definition of black magic, you'll often see that 'how parents curse their children' involves the 12th house. They called it cruelty, which I find to be quite apt, even today.
Yes... and how parents curse their children is pretty much what I was getting at above. Ancestral trauma or ancestral evil, handed down, usually unwittingly.
Sometimes it's very blatant, like in a case of an abused child becoming an abusive parent. Often, it's much more subtle. The child absorbs what the parents couldn't handle.
