This is one of the most fucked up things I have ever seen. And I have seen some fucked up shit (my mom's boyfriend's Asian cock to name just one) in my life.
Those kids, sadly, are not unlike most kids in America today. The difference is, those kids are literally sucking on mommy's swollen, nasty tit whereas the majority of American kids today are only doing it metaphorically. I see moms (and dads) whip out the metaphorical tit all the time to calm their nasty little fuckwads down. A tantrum needs to be dealt with swiftly and deftly and violently. Don't placate the little bastards because it makes your life easier, people. Do what the elders did, "You're eating the broccoli or you're going to bed hungry." Not "you don't like broccoli? Okay, I'm sorry I gave that to you, honey. Try some chicken fingers instead, okay?" All parents are losers. End of story. Merry Christmas.
Not too engorged with milk and latent Oedipal issues.
