Brenda's Child
This is a bit of a taboo subject and it makes people uncomfortable to talk about........ I love that. Excellent choice of subject matter.
The flow and the structure are also excellent. You tell the story well from start to finish. Especially since the ending is more implied than explicitly stated. I wish I was better at that. I am also jealous of the cry cry cry lines. So simple and so musical it's almost impossible to just say it.........you have to sing it.
I could definitely learn from this. I tend to write poems then turn them into songs. This is obviously a song from the get go.
Now to the nit picks.
There is a Tupac song called "Brenda's got a baby". That would bother me, but Brenda and baby do go well together. I'm not sure of another name that would work as well.
The terms Atari and joystick are both rather dated. If Brenda's baby boy was born in 93, he probably isn't playing Atari.

I don't know that I would use a brand name there because no matter what eventually it will sound dated as technology changes. Maybe just he fired up his game/games?
"He’d jerk the joystick back and forth" is a good line because of the alliteration there. Maybe He'd crank the controller back and forth? Controller refers to everything from Atari to Xbox controllers so it probably won't sound dated until the day when we plug our video games straight into our faces.
But in the end what he learned best
Was how to point and shoot……..
This line just bothered me on a philosophical level. Being a video game lover I take exception to the way video games are portrayed in the media as being "murder simulators" and "training" kids to kill.
I won't argue that point with you I can totally understand and respect that point of view.(that's not what we are here for anyway) If that is the point you are trying to make you nailed it, because it got a little rise out of me which means it is a well stated powerful lyric.
The only reason I mention it is that it might alienate younger listeners.
That being said I don't know how you could change it because it is so important to the story line.
I'll give this one a little more thought and see what I can come up with.
Great song though, I could definitely takes a few hints from your style.
Thanks for sharing.
