Ok, so I'm not even sure that the dude has kids, but I am 100% convinced that if he does, he is a ScreamFree Parent. Why am I so certain? Because every now and again he writes posts like this.
He's describing how doing the things that are right may be harder in the short term, but they are better and less expensive in the long run. Sure, keeping your cool while your baby screams bloody murder for the third hour in a row is no walk in the park. But doing anything else will cost you (and your child) much more heartache and stress down the road. Same for toddlers, kids, preteens, and even...teenagers.
