You tell them. You're tired of being told how to do a better job as a parent when you're worn to the bone with work, exhaustion and sleeplessness. You're running on fumes and you can barely see straight, and these fools want to hand you a rulebook. Why don't they hand you a bottle of wine? That would be a helpful parenting tool. That would get you back on the right track and put a smile on your face. This tee will tell them to spare you the lectures and hit the road.
