Hate to be the middle child here, but you both are correct.
I knew absolutely everything there was to know about parenting before I became a parent. Now I know I was sadly mistaken.
That being said, sometimes an "outside" point of view helps us see things we wouldn't otherwise see. Like the old Indian proverb goes: if you want to know what water is, don't ask the fish!
You two are both diplomats, and have calmed me down nicely. Thanks!
