The parental involvement is just a complication, not the main issue.  The main issue here is a selfish and immature "mom" who is putting her love life ahead of her child. She's the poster parent for why today's kids are so messed up.  After love, kids need stability, and she's one step away from Jerry Springer.

Fix your priorities, lady.  This child should be your #1 focus, and right now, he's just your collateral damage.  This kind of parenting is killing us, because these cute 3 year olds grow up into the angry teens who make the scrolling headlines.
