Definitely, but could be more along the lines of late miscarriages, still birth.. rather than a child actively being kept and raised by this ‘family’.
It’s difficult to come up with the ‘why’ of why someone would draw attention by abandoning 3 babies rather than just kill them & hide their bodies, as a previous poster mentioned. Abandoning an hour old baby is beyond cruel and twisted, but I suppose some people will rationalise ‘well I didn’t murder the child’, even though they could clearly die from exposure and lack of medical care. In my opinion, it probably boils down to a mix of religious beliefs and lack of education.
