I remember a similar and worse incident on a train, It pretty much scarred me for life. There were these two drunken bogans and the mother (if that's what you wanna call this bitch), was holding the baby in her lands. She was like, falling asleep while holding this baby. I was surprised she didn't drop it and let it roll down the train, like she did her beer bottle. At one point I thought the baby was going to fall (after she put it in the stroller), it was right of the edge.
I wanted to say "Hey, bitch. Take care of your kid.", but all I would have gotten out of that was sore knuckles and probably even a lawsuit. Maybe even a response like "Fuck OFF! Ya wog."
Again, taking the kids of the parent is like pretending that they have no trustworthy family, or that they can never change their ways. (Which is far from the truth.) Putting the parents through some program would be beneficial to them and the child. The program would have to involve check-ups, to make sure they don't get worse. eg; It reminds me of this hilarious comedian Russel Peters, a joke he made to call "child services", his father responded. "It's going to take 20+ minutes for them to get here, and in that time SOMEEEBODY gonna git hurt realll bad."
I lol'd, but that needs to be prevented.
