Uh oh. Unseen Risk Fallacy
Just because you don't experience risk, doesn't mean it does not exist. The company just hides risk from you, but it's still there, culminating without feedback.
As raising a child is a 19+ year project and the OP has already a few years of not stellar performance and risk - if not dealt with - grows exponentially (risk factors attrackt more risk factors).
So the stay in place is actually a very risky proposition. One huge bet, without much feedback.
As the OP is Young and doesn't have kids or other major spendings a much safer strategy would be to try different gigs. With his resume then (Google, lots of other gigs) he can prop. return to a low maintenance job at a big company at one point anyway.
