This is a Melt down.
Did the adult in this situation, based on limited data available to the casual observer, make good parenting choices? Maybe not.
I would like people to consider that they do not have all of the facts and that it is likely unfair to judge. I say this coming from experience with a kid like this. I’ve experienced major melt downs. Ones where I feared for the safety of anyone near my kid. One where I felt the safest choice was to call for police assistance. More than one where I felt helpless and could only cry. Many, especially in the early days, where I made poor parenting choices. Many where I’m sure someone judged me poorly.
My only point is that we have a very brief glimpse into this family’s lives. Please don’t judge.
