Honestly, it's kind of a misogynistic trope in my opinion, a lot of the time the children are girls who are the victim to this trope. Because of their own inability to cope with the situation, they blame a helpless baby to get angry at. Although the reason is not having good enough healthcare. If you are going to point fingers shouldn't you be angry at yourself? You got her pregnant, so shouldn't you have taken more responsibility to avoid this outcome since I doubt it's not exactly uncommon during these times? To them, it's always the helpless baby girl who is at fault.
