It's not even certain it's reasonably the fault of the 'system'. There's no details about how or why the mother died or why she happened to be alone with the baby for a few days. A mother taking care of a baby for a few days by herself is not a crazy circumstance without further context. At one point my wife had work and I had to take our toddler on a trip for a couple of days and no one could possibly have accused that situation of me being alone with our toddler due to some failure of the system, even if something had tragically killed me along the way.

There are so many stories about the system failing a baby or a mother, we don't need to extrapolate this specific incomplete story with such details until the actual details are available, which may or may not be consistent with the tragic failures of the system.
