I think atlantis is referring to the DailyMail's general hatred distrust of women -- it has a certain tendency to paint working mothers as selfish career-driven harridans and stay-at-home mothers as lazy good-for-nothing spongers. I don't actually think there's too much of that in this story, though.
It does seem rather unlikely that the child "nearly choked to death". To begin with, it sounds rather as though he gagged rather than choking at all, and it doesn't sound as though the plastic in question could have blocked his airway. Still not a good idea to have jagged bits of plastic in babyfood jars, of course, but I think parents have been bigging this up to the DailyMail ever so slightly.
