So evidently you've got to be careful about making big idealistic statements about cherishing every single moment. Because the moment you do, you're bound to be hit by a lot of testing of that ideal!
Kyle? Is a very loud kid. We first noticed this when he was not yet three months old, and it has not changed. When he's happy, he shouts with joy & excitement. When he's sad, he wails and keens. And when he's angry: screaming. Lots and lots of screaming.
Said screaming has lately been accompanied by slumping to the floor, putting his arms & head down, and generally becoming a puddle of 2-year-old unhappiness. And yes, I could say, "Feel free to scream outside" -- but that would torture the entire neighborhood. It would be easy to say "Feel free to scream in your room," but there's often a baby brother sleeping in the room next door, and who could sleep through that?
So it depends. I do love the happy times, though sometimes even that gleeful volume is hard to take. But those not-so-happy times? Those are the real test!
