I don't think she is comparing him to a child. I think she is saying that sometimes people behave badly because they lack the ability to understand and/or express what is really bothering them. A toddler having a tantrum is the canonical example of this, and has the advantage of having a large body of literature that explains how to deal with it, but if you think about it for more than a minute there are legions of adult examples. I did find the litany of toughness a bit grating, but clearly it is something that she needed to convince herself of, never mind other people. I think the article has some value as a parable, almost, that shows the value in not taking things personally.
